+<h1><a name="1"></a>1. General</h1>
+<h2><a name="1.1"></a>1.1 About this FAQ</h2>
+<blockquote><p>This FAQ was written and is maintained by Chris Allegretta <<a href="mailto:chrisa@asty.org">chrisa@asty.org</a>>, who also happens to be the creator of nano. Maybe someone else will volunteer to maintain this FAQ someday, who knows...</p></blockquote>
+<h2><a name="1.2"></a>1.2. How do I contribute to it?</h2>
+<blockquote><p>Your best bet is to send it to the nano email address, <a href="mailto:nano@nano-editor.org">nano@nano-editor.org</a> and if it is useful enough it will be included in future versions.</p></blockquote>
+<h2><a name="1.3"></a>1.3. What is GNU nano?</h2>
+<blockquote><p>GNU nano is designed to be a free replacement for the Pico text editor, part of the Pine email suite from <a href="http://www.washington.edu/pine/">The University of Washington</a>. It aims to "emulate Pico as closely as possible and perhaps include extra functionality".</p></blockquote>
+<h2><a name="1.4"></a>1.4. What is the history behind nano?</h2>
+<blockquote><p>Funny you should ask!</p>
+ <p><b>In the beginning...</b></p>
+ <p>For years Pine was THE program used to read email on a Unix system. The Pico text editor is the portion of the program one would use to compose his or her mail messages. Many beginners to Unix flocked to Pico and Pine because of their well organized, easy to use interfaces. With the proliferation of GNU/Linux in the mid to late 90's, many University students became intimately familiar with the strengths (and weaknesses) of Pine and Pico.</p>
+ <p><b>Then came Debian...</b></p>
+ <p>The <a href="http://www.debian.org/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but they were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>
+ <p><b>The event...</b></p>
+ <p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
+ <p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help menu, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is today.</p>
+ <p>In February 2001, nano was declared an official GNU program by Richard Stallman. Nano also reached its first production release on March 22, 2001.</p></blockquote>
+<h2><a name="1.5"></a>1.5. Why the name change from TIP?</h2>
+<blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program "establishes a full duplex terminal connection to a remote host", and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>
+<h2><a name="1.6"></a>1.6. What is the current version of nano?</h2>
+<blockquote><p>The current version of nano *should* be 1.2.2. Of course you should always check the nano homepage to see what the latest and greatest version is.</p></blockquote>

+<h2><a name="3.1"></a>3.1. How do install the RPM or DEB package?</h2>
+<blockquote><p>It's simple really! As root, type <b>rpm -Uvh nano-x.y.z-1.i386.rpm</b> if you have a RedHat-ish system or <b>dpkg -i nano_x.y.z-1.deb</b> if you have a Debian-ish system, where <b>x.y.z</b> is the release of nano. There are other programs to install packages, and if you wish to use those, knock yourself out.</p></blockquote>
+<h2><a name="3.2"></a>3.2. Compiling from source: WHAT THE HECK DO I DO NOW?</h2>
+<blockquote><p>Okay, take a deep breath, this really isn't hard. Unpack the nano source with a command like:</p>
+ <p><b>tar -zxvf nano-x.y.z.tar.gz</b></p>
+ <p>If you get error messages about the -z option, try this:</p>
+ <p><b>gzip -dc nano-x.y.z.tar.gz | tar xvf -</b></p>
+ <p>(again, where x.y.z is the version number in question). Then you need to run configure with any options you might want (if any).</p>
+ <p>The average case is this:</p>
+ <p><b>cd nano-x.y.z/</b><br>
+ <b>./configure</b><br>
+ <b>make</b><br>
+ <b>make install</b> (as root, of course)</p></blockquote>
+<h2><a name="3.3"></a>3.3. Why does everything go into /usr/local?</h2>
+<blockquote><p>Well, that's what the <b>configure</b> script defaults to. If you wish to change this, simply do this:</p>
+ <p><b>./configure --prefix=/usr</b></p>
+ <p>to put nano into /usr/bin when you run <b>make install</b>.</p></blockquote>
+<h2><a name="3.4"></a>3.4. I get errors about 'bindtextdomain', 'gettext' and/or 'gettextdomain'. What can I do about it?</h2>
+<blockquote><p>Try doing a <b>./configure --with-included-gettext</b> and see if that solves your problem. You may need to do a <b>make clean; make</b> to get it to work fully.</p></blockquote>
+<h2><a name="3.5"></a>3.5. Nano should automatically run strip on the binary when installing it!</h2>
+<blockquote><p>Actually, it does, but you have to use <b>make install-strip</b>. The default make install does not, and will not, run strip automatically.</p></blockquote>
+<h2><a name="3.6"></a>3.6. How can I make the executable smaller? This is too bloated!</h2>
+<blockquote><p>Actually, there are several parts of the editor that can be disabled. You can pass arguments to the <b>configure</b> script that disable certain features. Here's a brief list:</p>
+ <pre>
+ <b>--disable-tabcomp</b> Disables tab completion code for a smaller binary
+ <b>--disable-justify</b> Disable justify/unjustify function
+ <b>--disable-speller</b> Disables spell checker function
+ <b>--disable-help</b> Disables help function (^G)
+ <b>--disable-browser</b> Disables mini file browser
+ <b>--disable-wrapping</b> Disables all wrapping of text (and -w flag)
+ <b>--disable-mouse</b> Disables mouse support (and -m flag)
+ <b>--disable-operatingdir</b> Disable setting of operating directory</pre>
+ <p>There's also the <b>--enable-tiny</b> option which disables everything above, as well as some larger chunks of the program (like the marker code that you use Control-^ to select with). Also, if you know you aren't going to be using other languages you can use <b>--disable-nls</b> to disable internationalization and save a few K to a few dozen K depending on if you have locale support on your system. And finally there's always good old <b>strip</b> to strip all debugging code and code that exists in libraries on your system.</p>
+ <p>If, on the other hand, you can't live without bells and whistles, you could try:</p>
+ <pre>
+ <b>--enable-extra</b> Enable extra functions, including easter eggs
+ <b>--enable-nanorc</b> Enable use of .nanorc file
+ <b>--enable-color</b> Enables color and syntax highlighting
+ <b>--enable-multibuffer</b> Enables having multiple file buffers open
+ <b>--enable-all</b> Enables all of the above features</pre></blockquote>
+<h2><a name="3.7"></a>3.7. Tell me more about this multibuffer stuff!</h2>
+<blockquote><p>To use multiple file buffers, you must be using nano 1.1.12 or newer, and you must have configured nano with <b>--enable-multibuffer</b> or <b>--enable-extra</b> (use nano -V to check). Then when you want to enable inserting a file into its own buffer instead of into the current file, just hit <b>Meta-F</b>, then insert the file as normal with <b>^R</b>. If you always want files to be loaded into their own buffers, use the <b>--multibuffer</b> or <b>-F</b> flag when you invoke nano. </p>
+ <p>You can move between the buffers you have open with the <b>Meta-<</b> and <b>Meta-></b> keys, or more easily with <b>Meta-,</b> and <b>Meta-.</b> (clear as mud, right? =-). When you have more than one file buffer open, the ^X shortcut will say "Close", instead of the normal "Exit" when only one buffer is open.</p></blockquote>
+<h2><a name="3.8"></a>3.8. How do I make a .nanorc file that nano will read when I start it?</h2>
+<blockquote>It's not hard at all! But, your version of nano must have been compiled with <b>--enable-nanorc</b>, and again must be version 1.1.12 or newer (use nano -V to check your version and compiled features). Then simply copy the <b>nanorc.sample</b> that came with the nano source or your nano package (most likely in /usr/doc/nano) to .nanorc in your home directory. If you didn't get one, the syntax is simple. Flags are turned on and off by using the word <b>set</b> and the getopt_long flag for the feature, for example "set pico" or "set nowrap".</blockquote>

+ <p>Bourne shell users (like bash): <b>export TERM=vt100</b><br>
+ C Shell users (tcsh and csh): <b>setenv TERM vt100</b></p></blockquote>
+<h2><a name="4.2"></a>4.2. Nano crashes when I type <insert keystroke here>!</h2>
+<blockquote><p>If you aren't trying some bizarre keystroke combination with some bizarre $TERM entry, chances are you have found a bug. You are welcome to submit it to the <a href="mailto:nano-devel@gnu.org">nano-devel</a> list or to <a href="mailto:nano@nano-editor.org">nano@nano-editor.org</a>.</p></blockquote>
+<h2><a name="4.3"></a>4.3. Nano crashes when I resize my window. How can I fix that?</h2>
+<blockquote><p>Older versions of nano had this problem, please upgrade to a newer version (at least 0.9.9 would be great, 0.9.12 is recommended).</p></blockquote>
+<h2><a name="4.4"></a>4.4. [version 1.1.12 and earlier] Why does nano show ^\ in the shortcut list instead of ^J?</h2>
+<blockquote><p>The help (^G) and justify (^J) function were among the last to be written. To show the improvements that nano had over Pico (go to line # and replace), ^_ and ^\ were put on the shortcut list. Later, ^G came back in place of ^_ as it proved to be very valuable for new Unix users. If you use the <b>-p</b> option to nano (or hit Meta-P) you will get the same shortcuts at the bottom as Pico.</p></blockquote>
+<a name="4.5"></a>
+<h2><a name="4.5a"></a>4.5a. [version 1.1.12 and earlier] When I type in a search string, the string I last searched for is already in front of my cursor! What happened?!</h2>
+<blockquote><p>In nano version 0.9.20, the default is to have a completely consistent user interface across all user input functions. This means that regardless of whether you're being asked for a filename to insert or write, or a string to search for, the previous value is already inserted before the cursor. If you prefer the old behavior, use the Pico emulation mode (-p or --pico) or just hit Meta-P while in nano (see the ^G help text for more details).</p></blockquote>
+<h2><a name="4.5b"></a>4.5b. [version 1.2.2 and later] Hey, the search string behavior has reverted, it's now like Pico, what happened to the consistency?</h2>
+<blockquote><p>It was decided that consistency was nice, but people are used to Pico's inconsistent behavior. Also, in version 1.1.99pre1, search and replace history was introduced. If you wish to edit your previous search/replace entry (or any previous entry), you can do so by hitting the up arrow to cycle through your history. This method allows the best of both worlds: You don't need to erase the previous string if you want to enter a new one, but you can with one keystroke recall previous entries for editing. Therefore there is now no "Pico mode", nano is and has always been a Pico <b>clone</b>, and clones by default should be compatible.</p></blockquote>
+<h2><a name="4.6"></a>4.6. I get the message "NumLock glitch detected. Keypad will malfunction with NumLock off." What gives?</h2>
+<blockquote><p>Nano (and actually almost all console editors) has issues when cycling the NumLock key in certain X terminals (rxvt, aterm, wterm, etc...). When you switch NumLock from on to off, you put the terminal into an "application mode" that changes what sequences are sent by the keypad. These sequences vary sufficiently from terminal to terminal that it is nearly impossible to work around them from within nano.</p>
+ <p>In a nutshell, if you want to be able to use the keypad with the arrow and page up/down functionality, you have to exit nano and reset your terminal (presumably with "reset" or "stty sane" or similar) and then run nano again with NumLock off. If you know an easier way to restore "normal mode", please mail <a href="mailto:nano@nano-editor.org">nano@nano-editor.org</a>.</p></blockquote>
+<h2><a name="4.7"></a>4.7. How do I make nano my default editor (in Pine, mutt, etc.)?</h2>
+<blockquote><p>You need to make nano your $EDITOR. If you want this to be saved, you should put a line like this in your <b>.bashrc</b> if you use bash (or <b>.zshrc</b> if you believe in zsh):</p>
+ <p><b>export EDITOR=/usr/local/bin/nano</b></p>
+ <p>or if you use tcsh put this in your <b>.cshrc</b> file:</p>
+ <p><b>setenv EDITOR /usr/local/bin/nano</b></p>
+ <p>Change /usr/local/bin/nano to wherever nano is installed on your system. Type "which nano" to find out. This will not take effect until the next time you login. So log out and back in again.</p>
+ <p>Then on top that if you use Pine you must go into setup (type <b>S</b> at the main menu), then configure (type <b>C</b>). Hit enter on the lines that say:</p>
+ <p><b>[ ] enable-alternate-editor-cmd</b><br>
+ <b>[ ] enable-alternate-editor-implicitly</b></p>
+ <p>Then exit (<b>E</b>) and select Yes (<b>Y</b>).</p>
+ <p>Mutt users should see an effect immediately the next time you log in, no further configuration is needed. However, if you want to let people know you use nano to compose your email messages, you can put a line like this in your <b>.muttrc</b>:</p>
+ <p><b>my_hdr X-Composer: nano x.y.z</b></p>
+ <p>Again, replace x.y.z with the version of nano you use.</p></blockquote>
+<h2><a name="4.8"></a>4.8. I've compiled nano with color support, but I don't see any color when I run it!</h2>
+<blockquote><p>If you want nano to actually use color, you have to specify the color configurations you want it to use in your .nanorc. Some example configurations are in the <b>nanorc.sample</b> that comes with the nano source or your nano package. See Section <a href="#3.8">3.8</a>.</p></blockquote>

+<h1><a name="5"></a>5. Internationalization</h1>
+<h2><a name="5.1"></a>5.1. There's no translation for my language!</h2>
+<blockquote><p>On June of 2001, GNU nano entered the <a href="http://www.iro.umontreal.ca/contrib/po/HTML/">Free Translation Project</a> and since then, translations should be managed from there.</p>
+ <p>If there isn't a translation for your language, you could ask <a href="http://www.iro.umontreal.ca/contrib/po/HTML/teams.html">your language team</a> to translate nano, or better still, join your team and do it yourself. Joining a team is easy. You just need to ask the <a href="mailto:translation@iro.umontreal.ca">TP coordinator</a> to add you to your team, and send a <a href="http://www.iro.umontreal.ca/contrib/po/HTML/disclaim.html">translation disclaimer to the FSF</a> (this is necessary as nano is an official GNU package, but it does <b>not</b> mean that you transfer the rights of your work to the FSF, it's just so the FSF can legally manage them).</p>
+ <p>In any case, translating nano is very easy. Just grab the <b>nano.pot</b> file from the latest and greatest nano distribution (it's in the <b>po/</b> directory) and translate each line into your native language on the <b>msgstr</b> line. When you're done, you should send it to the TP's central po repository.</p></blockquote>
+<h2><a name="5.2"></a>5.2. I don't like the translation for <x> in my language. How can I fix it?</h2>

+<h2><a name="6.2"></a>6.2. Why should I use Pico instead of nano?</h2>
+<blockquote><p>Again, check out the <a href="http://www.nano-editor.org/">nano homepage</a> for a good summary of reasons. It really is a matter of personal preference as to which editor you should use. If you're the type of person who likes using the original version of a program, then Pico is the editor for you. If you're looking for a few more features and a 'better' license as far as adding your own changes (sacrificing mailer integration with Pine), nano is the way to go.</p></blockquote>
+<h2><a name="6.3"></a>6.3. What is so bad about the Pine license?</h2>
+<blockquote><p>The U of W license for Pine and Pico is not considered truly Free Software according to both the Free Software Foundation and the <a href="http://www.debian.org/social_contract#guidelines">Debian Free Software Guidelines</a>. The main problem regards the limitations on distributing derived works: according to UW, you can distribute their software, and you can modify it, but you can not do both, i.e. distribute modified binaries.</p></blockquote>
+<h2><a name="6.4"></a>6.4. Okay, well what mail program should I use then?</h2>
+<blockquote><p>If you are looking to use a Free Software program similar to Pine and emacs is not your thing, you should definitely take a look at <a href="http://www.mutt.org/">mutt</a>. It is a full-screen, console based mail program that actually has a lot more flexibility than Pine, but has a keymap included in the distribution that allows you to use the same keystrokes as Pine would to send and receive mail. It's also licensed under the GPL.</p></blockquote>
+<h2><a name="6.5"></a>6.5. Why doesn't UW simply change their license?</h2>
+<blockquote><p>You're really not asking the right person here. I (Chris) waited a long time to see if UW would change their license because of the amount of high quality software being released and developed under the GPL without being taken advantage of by malicious corporate entities or other baddies, but no such luck so far.</p></blockquote>
+<h2><a name="6.6"></a>6.6. What if tomorrow UW changes the license to be truly Free Software?</h2>
+<blockquote><p>Honestly nothing would make me happier than to see that happen. Nano would continue to be developed independently until such time as Pico had all the features nano did or the projects merged. That just does not seem very likely given that there has been no sign of any changes in the past few years in a positive direction.</p></blockquote>

+<blockquote><p>See Section <a href="#7.2">7.2</a>.</p></blockquote>
+<h2><a name="7.4"></a>7.4. How do I join the development team?</h2>
+<blockquote><p>The easiest way is to consistently send in good patches that add some needed functionality, fix a bug or two and/or make the program more optimized/efficient. Then ask nicely and you will probably be added to the Savannah development list and be given CVS write access after awhile. There is a lot of responsibility that goes along with being a team member, so don't think it's just something to add to your resume.</p></blockquote>

+qui devrait être livré avec \fBnano\fP.
+
+.SH NOTES
+Dans certains cas, \fBnano\fP essaiera de sauvegarder le fichier en
+cours d'édition dans un fichier de secours. Cela arrivera
+principalement si \fBnano\fP reçoit un signal SIGHUP ou SIGTERM, ou
+bien se trouve à court de mémoire. Le nom de ce fichier de secours sera
+\fInano.save\fP si le fichier en cours n'avait pas encore de nom, ou
+sera composé du nom du fichier en cours suivi du suffixe «\ .save\ ». Si
+un fichier de ce nom existe déjà dans le répertoire, un «\ .save\ » et
+un nombre seront ajoutée à la fin du nom du fichier en cours afin de le
+rendre unique (par exemple, «\ .save.1\ »). En mode multifichiers,
+\fBnano\fP réalisera une sauvegarde de tous les fichiers en cours dans
+leurs fichiers de secours respectifs.

+.SH NAME
+nanorc \- fichier de configuration de l'éditeur nano du projet GNU
+
+.SH DESCRIPTION
+Cette page de manuel décrit brièvement le fichier de configuration de
+l'éditeur \fBnano\fP du projet GNU.
+.PP
+\fBnano\fP est un petit éditeur sympathique et libre, qui vise à
+remplacer Pico, l'éditeur par défaut du paquet non-libre Pine.
+\fBnano\fP ne se contentant pas de copier l'interface et l'ergonomie de
+Pico, il offre également certaines fonctionnalités manquantes (ou
+désactivées par défaut) de Pico. Ces fonctionnalités sont, par exemple,
+les fonctions de recherche et de remplacement, et la possibilité de
+sauter directement à un numéro de ligne.
+.PP
+Le fichier \fInanorc\fP contient les paramètres par défaut de
+\fBnano\fP. Lors de son démarrage, nano commence par lire le fichier de
+configuration général \fI$SYSCONFDIR/nanorc\fP, puis lit le fichier de
+configuration personnel de l'utilisateur \fI~/.nanorc\fP.
+
+.SH OPTIONS
+Le fichier de configuration accepte une série de commandes «\ set\ »
+(activer) et «\ unset\ » (désactiver), qui permettent de définir la
+configuration de nano au démarrage sans avoir à utiliser d'options sur
+la ligne de commande.
+De plus, les mots clefs «\ syntax\ » (syntaxe) et «\ color\ » (couleur)
+sont utilisés pour définir les règles de colorisation pour différents
+motifs de texte. Nano lira une commande par ligne.
+
+Les options du fichier de configuration ont priorité sur les valeurs par
+défaut utilisées par nano. Les options données sur la ligne de commande
+permettent d'outrepasser les options du fichier de configuration.
+
+Les options sont désactivées (unset) par défaut, sauf les options
+prenant un argument.
+
+Les commandes et arguments reconnus sont\ :
+
+.TP 3
+\fBset/unset autoindent\fP
+Active l'indentation automatique.
+.TP
+\fBset/unset backup\fP
+Crée des copie de sécurité appelées
+.IR nom_du_fichier~ .
+.TP
+\fBset/unset const\fP
+Affiche en permanence la position du curseur dans la barre
+d'information.
+.TP
+\fBset/unset cut\fP
+Par défaut, utilise ^K pour couper le texte du curseur à la fin de la
+ligne, au lieu de couper la ligne entière.
+.TP
+\fBset fill \fIn\fP\fP
+Passe automatiquement à la ligne à la colonne \fIn\fP. Si la valeur
+indiquée est 0 ou moins, la longueur de la ligne sera égale à la largeur
+de l'écran moins \fIn\fP. La valeur par défaut est -8.
+.TP
+\fBset/unset historylog\fP
+Active l'utilisation de
+.I ~/.nano_history
+pour enregistrer et relire les chaînes ayant fait l'objet d'une
+recherche ou d'un remplacement.
+.TP
+\fBset/unset keypad\fP
+Utilise l'autre gestion du pavé numérique.
+.TP
+\fBset/unset multibuffer\fP
+Permet de charger simultanément plusieurs fichiers.
+.TP
+\fBset/unset noconvert\fP
+Pas de conversion depuis les formats DOS et Mac.
+.TP
+\fBset/unset nofollow\fP
+Ne suit pas les liens symboliques lors de l'écriture des fichiers.
+.TP
+\fBset/unset nohelp\fP
+Désactive la barre d'aide affichée en bas de l'écran.
+.TP
+\fBset/unset nowrap\fP
+Désactive le passage automatique à la ligne.
+.TP
+\fBset operatingdir "\fIrépertoire\fP"\fP
+\fBnano\fP ne lira et n'écrira des fichiers qu'à l'intérieur du
+\fIrépertoire\fP et de ses sous-répertoires. De plus, celui-ci devient
+le répertoire courant, afin que les fichiers soient écrits dans ce
+dossier. Par défaut, cette fonction est désactivée.
+.TP
+\fBset/unset preserve\fP
+Préserve les séquences XON et XOFF (^Q et ^S).
+.TP
+\fBset quotestr "\fIchaîne\fP"\fP
+Définit le préfixe par défaut utilisé pour les citations dans les
+courriers électroniques. Ce préfixe est utilisé pour réaliser une
+justification correcte de ces citations. Il s'agira, si votre système le
+permet, d'une «\ expression rationnelle étendue\ ». Dans le cas
+contraire, il s'agira d'une chaîne de texte brut. Si vous disposez des
+expressions rationnelles, la valeur par défaut sera\ :
+
+ set quotestr "^([\ \\t]*[|>:}#])+"
+
+Sinon, ce sera ">\ ". Notez que le «\ \\t\ » ci-dessus correspond à un
+caractère de tabulation.
+.TP
+\fBset/unset regexp\fP
+Utilise par défaut des expressions rationnelles pour les recherches.
+.TP
+\fBset/unset smooth\fP
+Active le défilement ligne-par-ligne du texte.
+.TP
+\fBset speller \fIprogramme\fP\fP
+Utilise le correcteur orthographique \fIprogramme\fP au lieu du
+correcteur intégré, qui s'appuie sur \fIspell\fP.
+.TP
+\fBset/unset suspend\fP
+Autorise à suspendre nano avec ^Z.
+.TP
+\fBset tabsize \fIn\fP\fP
+Utilise une largeur de tabulation de \fIn\fP au lieu de la valeur par
+défaut (8). Cette valeur doit être supérieur à 0.
+.TP
+\fBset/unset tempfile\fP
+S'il a été modifié, le fichier sera sauvegardé automatiquement
+sans demande de confirmation.
+.TP
+\fBset/unset view\fP
+Interdit la modification du fichier.
+.TP
+.B syntax "\fIchaîne\fP" ["\fImotif_de_fichier\fP" ... ]
+Définit une syntaxe nommée \fIchaîne\fP qui pourra être activé via
+l'option \fB-Y\fP, ou qui sera automatiquement activé si le nom du
+fichier en cours correspond au \fImotif_de_fichier\fP. Toutes les
+instructions de colorisation \fBcolor\fP suivantes s'appliqueront à cette
+syntaxe, jusqu'à la définition d'une nouvelle syntaxe.
+.TP
+.B color \fIcouleur_texte\fP[,\fIcouleur_fond\fP] "\fImotif\fP" ...
+Pour la syntaxe en cours, affiche toutes les expressions correspondant à
+l'expression rationnelle \fImotif\fP en utilisant la couleur de texte
+\fIcouleur_texte\fP et éventuellement la couleur de fond
+\fIcouleur_fond\fP. Les couleurs acceptées par \fBnano\fP pour le
+texte et le fond sont\ : \fIwhite\fP (blanc), \fIblack\fP (noir),
+\fIred\fP (rouge), \fIblue\fP (bleu), \fIgreen\fP (vert), \fIyellow\fP
+(jaune), \fImagenta\fP, et \fIcyan\fP. Vous pouvez ajouter à
+ces couleurs le préfixe \fIbright\fP pour obtenir une couleur plus
+lumineuse. Si votre terminal est capable de gérer la transparence, ne
+pas spécifier de \fIcouleur_fond\fP indique à \fBnano\fP d'essayer
+d'utiliser un fond transparent.
+.TP
+.B color \fIcouleur_texte\fP[,\fIcouleur_fond\fP] start="\fImotif_début\fP" end="\fImotif_fin\fP"
+Affiche les expressions commençant par \fImotif_début\fP et se terminant
+par \fImotif_fin\fP en utilisant la couleur de texte \fIcouleur_texte\fP
+et éventuellement la couleur de fond \fIcouleur_fond\fP. Cela permet à
+la colorisation syntaxique de s'étendre sur plusieurs lignes. Notez que
+toutes les occurrences successives de \fImotif_début\fP après le
+\fImotif_début\fP initial seront colorées jusqu'à la prochaine instance
+de \fImotif_fin\fP.

+.B \-R (\-\-regexp)
+Enable regular expression matching for search strings, as well as
+\\n subexpression replacement for replace strings, if available.
+.TP
+.B \-S (\-\-smooth)
+Enable smooth scrolling. Text will scroll line-by-line, instead of the
+usual chunk-by-chunk behavior.

+
+.SH INITIALIZATION FILE
+\fBnano\fP will read initialization files in the following order:
+.IR SYSCONFDIR/nanorc ,
+then
+.IR ~/.nanorc .
+Please see
+.BR nanorc (5)
+and the example file \fBnanorc.sample\fP which should be provided with
+\fBnano\fP.
+
+.SH NOTES
+\fBnano\fP will try to dump the buffer into an emergency file in some
+cases. Mainly, this will happen if \fBnano\fP receives a SIGHUP or
+SIGTERM or runs out of memory, when it will write the buffer into a file
+named
+.I nano.save
+if the buffer didn't have a name already, or will add a ".save" suffix
+to the current filename. If an emergency file with that name already
+exists in the current directory, ".save" and a number (e.g. ".save.1")
+will be suffixed to the current filename in order to make it unique. In
+multibuffer mode, \fBnano\fP will write all the open buffers to the
+respective emergency files.
+
+.SH BUGS
+Please send any comments or bug reports to
+.BR nano@nano-editor.org .
+
+The \fBnano\fP mailing list is available from
+.BR nano-devel@gnu.org .
+
+To subscribe, email to
+.B nano-devel-request@gnu.org

+.SH NAME
+nanorc \- GNU nano's rcfile
+.SH DESCRIPTION
+This manual page documents GNU \fBnano\fP's rcfile.
+.PP
+\fBnano\fP is a small, free and friendly editor which aims to replace
+Pico, the default editor included in the non-free Pine package. Rather
+than just copying Pico's look and feel, \fBnano\fP also implements some
+missing (or disabled by default) features in Pico, such as "search and
+replace" and "go to line number".
+.PP
+The \fInanorc\fP file contains the default settings for \fBnano\fP.
+During startup, \fBnano\fP will first read its system-wide settings from
+.IR SYSCONFDIR/nanorc ,
+and then user-specific settings from
+.IR ~/.nanorc .
+
+.SH OPTIONS
+The configuration file accepts a series of "set" and "unset" commands,
+which can be used to configure nano on startup without using the
+command-line options. Additionally, the "syntax" and "color" keywords
+are used to define syntax highlighting rules for different text
+patterns. GNU nano will read one command per line.
+
+Options in rcfiles take precedence over nano's defaults, and command
+line options override rcfile settings.
+
+Options are unset by default, except for options that take an argument.
+
+The supported commands and arguments are:
+
+.TP 3
+\fBset/unset autoindent\fP
+Use auto-indentation.
+.TP
+\fBset/unset backup\fP
+Create backup files in
+.IR filename~ .
+.TP
+\fBset/unset const\fP
+Constantly display the cursor position in the status bar.
+.TP
+\fBset/unset cut\fP
+Use cut to end of line with ^K by default.
+.TP
+\fBset fill \fIn\fP\fP
+Wrap lines at column number \fIn\fP. If \fIn\fP is 0 or less, the line
+length will be the screen width less \fIn\fP. The default value is -8.
+.TP
+\fBset/unset historylog\fP
+Enable
+.I ~/.nano_history
+for saving and reading search/replace strings.
+.TP
+\fBset/unset multibuffer\fP
+Allow inserting files into their own buffers.
+.TP
+\fBset/unset noconvert\fP
+Don't convert files from DOS/Mac format.
+.TP
+\fBset/unset nofollow\fP
+Don't follow symlinks when writing files.
+.TP
+\fBset/unset nohelp\fP
+Don't display the help lists at the bottom of the screen.
+.TP
+\fBset/unset nowrap\fP
+Don't wrap text at all.
+.TP
+\fBset operatingdir "\fIdirectory\fP"\fP
+\fBnano\fP will only read and write files inside \fIdirectory\fP and its
+subdirectories. Also, the current directory is changed to here, so
+files are inserted from this dir. By default the operating directory
+feature is turned off.
+.TP
+\fBset/unset preserve\fP
+Preserve the XON and XOFF keys (^Q and ^S).
+.TP
+\fBset quotestr "\fIstring\fP"\fP
+The email-quote string, used to justify email-quoted paragraphs. This
+is an "extended regular expression" if your system supports them,
+otherwise a literal string. The default value is
+
+ set quotestr "^([\ \\t]*[|>:}#])+"
+
+if you have regexps, otherwise set quotestr ">\ ". Note that '\\t'
+above stands for a literal Tab character.
+.TP
+\fBset/unset rebinddelete\fP
+Interpret the Delete key differently so that both Backspace and Delete
+work properly. You should only need to use this option if Backspace
+acts like Delete on your system.
+.TP
+\fBset/unset regexp\fP
+Do regular expression searches by default.
+.TP
+\fBset/unset smooth\fP
+Use smooth scrolling by default.
+.TP
+\fBset speller \fIspellprog\fP\fP
+Use spelling checker \fIspellprog\fP instead of the built-in one, which
+calls \fIspell\fP.
+.TP
+\fBset/unset suspend\fP
+Allow nano to be suspended with ^Z.
+.TP
+\fBset tabsize \fIn\fP\fP
+Use a tab size of \fIn\fP instead of the default (8); must be greater
+than 0.
+.TP
+\fBset/unset tempfile\fP
+Save automatically on exit, don't prompt.
+.TP
+\fBset/unset view\fP
+Disallow file modification.
+.TP
+.B syntax "\fIstr\fP" ["\fIfileregex\fP" ... ]
+Defines a syntax named \fIstr\fP which can be activated via the \fB-Y\fP
+flag, or will be automatically activated if the current filename matches
+\fIfileregex\fP. All following \fBcolor\fP statements will apply to
+\fIsyntax\fP until a new syntax is defined.
+.TP
+.B color \fIfgcolor\fP[,\fIbgcolor\fP] "\fIregex\fP" ...
+For the currently defined syntax, display all expressions matching
+\fIregex\fP with foreground color \fIfgcolor\fP and optional background
+color \fIbgcolor\fP. Legal colors for foreground and background color
+are: white, black, red, blue, green, yellow, magenta, and cyan. You may
+use the prefix "bright" to force a stronger color highlight. If your
+terminal supports transparency, not specifying a \fIbgcolor\fP tells
+\fBnano\fP to attempt to use a transparent background.
+.TP
+.B color \fIfgcolor\fP[,\fIbgcolor\fP] start="\fIsr\fP" end="\fIer\fP"
+Display expressions which start with \fIsr\fP and end with \fIer\fP
+with foreground color \fIfgcolor\fP and optional background color
+\fIbgcolor\fP. This allows syntax highlighting to span multiple lines.
+Note that all subsequent instances of \fIsr\fP after an initial \fIsr\fP
+is found will be highlighted until the first instance of \fIer\fP.

+@section Command Line Options
+
+@code{nano} takes the following options from the command line:
+
+@table @code
+
+@item -B, --backup
+When saving a file, back up the previous version of it to the current
+filename suffixed with a ~.
+
+@item -D, --dos
+Write file in DOS format.
+
+@item -F, --multibuffer
+Enable multiple file buffers, if available.
+
+@item -I, --ignorercfiles
+Don't look at SYSCONFDIR/nanorc or ~/.nanorc, if nanorc support is
+available.
+
+@item -M, --mac
+Write file in Mac format.
+
+@item -N, --noconvert
+Do not convert files from DOS/Mac format.
+
+@item -Q [str], --quotestr [str]
+Set the quoting string for justifying. The default is
+
+@quotation
+@code{^([ \t]*[|>:@}#])+}
+@end quotation
+
+if regular expression support is available, or ``> '' otherwise. Note
+that @code{\t} above stands for a literal Tab character.
+
+@item -R, --regexp
+Turn on regular expression search and search/replace.
+
+@item -S, --smooth
+Enable smooth scrolling.
+
+@item -T [num], --tabsize=[num]
+Set the displayed tab length to [num] columns.
+
+@item -V, --version
+Print the version number and copyright and quit.
+
+@item -Y, --syntax=[str]
+Specify a specific syntax highlighting from the .nanorc to use, if
+available.
+
+@item -c, --const
+Constantly display the cursor position and line number on the statusbar.
+
+@item -d, --rebinddelete
+Interpret the Delete key differently so that both Backspace and Delete
+work properly. You should only need to use this option if Backspace
+acts like Delete on your system.
+
+@item -h, --help
+Print the usage and exit.
+
+@item -i, --autoindent
+Automatically indent new lines to the same number of spaces and tabs as
+the previous line.
+
+@item -k, --cut
+Makes ^K cut from the current cursor position to the end of the current
+line.
+
+@item -l, --nofollow
+When writing files, if the given file is a symbolic link it is removed
+and a new file is created.
+
+@item -m, --mouse
+Enables the use of the mouse to select text (currently only useful for
+running under the X window system).
+
+@item -o [dir], --operatingdir=[dir]
+Set operating directory. Makes @code{nano} set up something similar to
+a chroot.
+
+@item -p, --preserve
+Preserve the ^Q (XON) and ^S (XOFF) sequences so data being sent to the
+editor can be can be stopped and started.
+
+@item -r [#cols], --fill=[#cols].
+Wrap lines at column #cols. By default this is the width of the screen,
+less eight. If this value is negative, wrapping will occur at #cols
+from the right of the screen, allowing it to vary along with the screen
+width if the screen is resized.
+
+@item -s [prog], --speller=[prog]
+Invoke [prog] as the spell checker. By default, @code{nano} uses its
+own interactive spell checker that requires the @code{spell} program be
+installed on your system.
+
+@item -t, --tempfile
+Do not ask whether or not to save the current contents of the file when
+exiting, assume yes. This is most useful when using @code{nano} as the
+composer of a mailer program.
+
+@anchor{Expert Mode}
+@item -x, --nohelp
+In Expert Mode, the Shortcut Lists will not appear at the bottom of the
+screen. This affects the location of the statusbar as well, as in
+Expert Mode it is located at the very bottom of the editor.
+
+Note: When accessing the help system, Expert Mode is temporarily
+disabled to display the help system navigation keys.
+
+@item -v, --view
+Do not allow the contents of the file to be altered. Note that this
+flag should NOT be used in place of correct file permissions to
+implement a read-only file.
+
+@item -w, --nowrap
+Do not wrap long lines at any length. This option overrides any value
+for -r.
+
+@item -z, --suspend
+Enable suspend ability of @code{nano} using the system's suspend
+keystroke (usually ^Z).
+
+@item -a, -b, -e, -f, -g, -j
+Ignored, for compatibility with Pico.
+
+@item +LINE
+Start at line number LINE instead of the default of line 1.

+@node Special Functions, The Titlebar, Entering Text, Editor Basics
+@section Special Functions
+
+Special functions use the Control key (displayed in the help and
+shortcut lists as ^), the Meta key (displayed as M), or the Esc key.
+
+@itemize @bullet
+@item
+Control key sequences are entered by holding down the Control key and
+pressing the desired key, or by pressing the Esc key twice and pressing
+the desired key.
+@item
+Pressing Esc twice and then typing a three-digit number from 000 to 255
+will enter the character with the corresponding ASCII code.
+@item
+Meta key sequences can be entered in a number of possible ways: Pressing
+the Escape key, then releasing it and pressing the desired key, or
+holding down the Alt key while pressing the desired key. This varies
+from keyboard to keyboard, and certain commercial operating systems
+``swallow'' the Alt key so that it never reaches the application. If
+your operating system does this, you should use the Escape key to
+generate Meta key sequences.

+@section The Titlebar
+
+The titlebar is the line displayed at the top of the editor. There are
+three sections: left, center and right. The section on the left
+displays the version of @code{nano} being used. The center section
+displays the current file name, or ``New Buffer'' if the file has not
+yet been named. The section on the right will display ``Modified'' if
+the file has been modified since it was last saved or opened.
+
+Special modes: When @code{nano} is in ``File browser'' mode, the center
+section will display the current directory instead of the filename.

+
+The online help system in @code{nano} is available by pressing ^G.
+It is fairly self explanatory, documenting the various parts of the
+editor and available keystrokes. Navigation is via the ^Y (Page Up)
+and ^V (Page Down) keys. ^X exits the help system.
+
+
+@node Feature Toggles, The File Browser, Online Help, Top
+@chapter Feature Toggles
+
+Toggles allow you to change certain aspects of the editor that
+would normally be done via command line flags. They are invoked via
+certain Meta key sequences. @xref{Special Functions}, for more info.
+The following global toggles are available:
+
+@table @code
+
+@item Backup File Toggle (Meta-B)
+toggles the -B (@code{--backup}) command line flag.
+
+@item DOS Format Toggle (Meta-D)
+toggles the -D (@code{--dos}) command line flag.
+
+@item Multiple Files Toggle (Meta-F)
+toggles the -F (@code{--multibuffer}) command line flag.
+
+@item AutoIndent Toggle (Meta-I)
+toggles the -i (@code{--autoindent}) command line flag.
+
+@item Cut To End Toggle (Meta-K)
+toggles the -k (@code{--cut}) command line flag.
+
+@item Mouse Toggle (Meta-M)
+toggles the -m (@code{--mouse}) command line flag.
+
+@item Mac Format Toggle (Meta-O)
+toggles the -M (@code{--mac}) command line flag.
+
+@item Smooth Scrolling Toggle (Meta-S)
+toggles the -S (@code{--smooth}) command line flag.
+
+@item AutoWrap Toggle (Meta-W)
+toggles the -w (@code{--nowrap}) command line flag.
+
+@item Expert/Nohelp Toggle (Meta-X)
+toggles the -x (@code{--nohelp}) command line flag.
+
+@item Suspend Toggle (Meta-Z)
+toggles the -z (@code{--suspend}) command line flag.
+

+@chapter The File Browser
+
+When reading or writing files, pressing ^T will invoke the file browser.
+Here, one can navigate directories in a graphical manner in order to
+find the desired file.
+
+Basic movement in the file browser is accomplished with the arrow keys
+and page up/down. The behavior of the enter (or `s') key varies by what
+is currently selected. If the currently selected object is a directory,
+the file browser will enter and display the contents of the directory.
+If the object is a file, this filename and path are copied to the
+statusbar and the file browser is exited.
+
+@node Pico Compatibility, Building and Configure Options, The File Browser, Top
+@chapter Pico Compatibility
+
+@code{nano} attempts to emulate Pico as closely as possible, but there
+are certain differences between the editors:
+
+@table @code
+@item Search and Replace History
+As of version 1.2.2 of @code{nano}, text entered as search or replace
+strings will be stored and can be accessed with the up/down arrow keys.
+Previously, @code{nano} offered a more consistent, but incompatible with
+Pico, method for entering search and replace strings. In the old
+method, previous entries would be displayed by default as editable text
+in front of the cursor, as opposed to being bracketed and uneditable as
+it is in Pico. The old behavior could be made compatible with Pico via
+the @code{-p} flag, but recent versions of Pico use the @code{-p} flag
+to preserve the XON and XOFF sequences within the editor. Since with
+the new method search and replace strings can still be edited by simply
+hitting the up arrow key once, the old method was removed completely.
+
+
+@item Writing or Appending Selected Text to Files
+Text selected using the Control-Caret (^^) key can be written out or
+appended to a new or existing file using the Writeout key (^O).
+
+@item Toggles
+Many options which alter the functionality of the program can be
+"toggled" on or off using Meta key sequences, meaning the program does
+not have to be restarted to turn a particular feature of the editor on
+or off. Please see the internal help function (^G) for a list of what
+functions can be toggled for a particular version of @code{nano}. Also
+see @xref{Feature Toggles}, though this may be out of date.
+
+@item Cursor Position Display
+The output of the "Display Cursor Position" in @code{nano} displays
+the given column position, as well as the row and total character
+position of the cursor.
+
+@item Interactive Replace and Spell Checker
+It is worth noting that the @code{nano} replace function is interactive,
+i.e, it does not stop after one search string is found and automatically
+replace it. The @code{nano} implementation will stop at each search
+string found and query whether to replace this instance or not. The
+internal spell checker operates similarly. Note that these is no way to
+force these functions to behave in the Pico fashion. As of version
+1.2.2, misspelled words are sorted and trimmed for uniqueness in the
+internal spell checker such that the words 'apple' and 'Apple' will be
+prompted for correction separately.
+@end table
+
+@node Building and Configure Options, , Pico Compatibility, Top
+@chapter Building and Configure Options
+
+Building @code{nano} from source is fairly straightforward if you are
+familiar with compiling programs with autoconf support:
+
+@itemize @bullet
+@item tar xvfz nano-x.y.z.tar.gz (where x.y.z is the version of nano)
+@item cd nano-x.y.z/
+@item ./configure
+@item make
+@item make install
+@end itemize
+
+if you are looking to optimize @code{nano} for size, you may want to
+consider the following command line options:
+
+
+@table @code
+
+@item --disable-tabcomp
+Disable the tab completion code when reading or writing files.
+
+@item --disable-justify
+Disable the justify (^J)/unjustify (^U) functions in the editor.
+
+@item --disable-speller
+Disable spell checker ability.
+
+@item --disable-help
+Disable the help function (^G). Disabling this option makes the binary
+much smaller, but makes it difficult for new users to learn more than
+very basic things about using the editor.
+
+@item --disable-browser
+Disable the mini file browser (^T) when reading or writing files.
+
+@item --disable-mouse
+Disable all mouse functionality. This also disables the -m command line
+flag, which enables the mouse functions.
+
+@item --disable-operatingdir
+Disable setting the operating directory. This also disables the -o
+command line flag.
+
+@item --enable-tiny
+This option disables all the above. It also disables some of the larger
+internals of the editor, like the marker code (^^) and the cut to line
+(-k) option, which depends on the marker code to work properly. It also
+disables the function toggles.
+
+@item --disable-wrapping
+Disable all word wrapping in the editor. This also eliminates the -w
+command line flag, as nonwrapping is then the default behavior.
+
+@item --disable-nls
+Disables Native Language support. This will make the available GNU
+@code{nano} translations unusable.
+
+@item --with-slang
+Compiling GNU @code{nano} with Slang is supported, and will make the
+binary notably smaller than if compiled with ncurses or other curses
+libraries.

-<hr width="100%">
-<h1><a name="1"></a>1. General</h1>
-<h2><a name="1.1"></a>1.1 About this FAQ</h2>
-<blockquote><p>This FAQ was written and is maintained by Chris Allegretta <<a href="mailto:chrisa@asty.org">chrisa@asty.org</a>>, who also happens to be the creator of nano. Maybe someone else will volunteer to maintain this FAQ someday, who knows...</p></blockquote>
-<h2><a name="1.2"></a>1.2. How do I contribute to it?</h2>
-<blockquote><p>Your best bet is to send it to the nano email address, <a href="mailto:nano@nano-editor.org">nano@nano-editor.org</a> and if it is useful enough it will be included in future versions.</p></blockquote>
-<h2><a name="1.3"></a>1.3. What is GNU nano?</h2>
-<blockquote><p>GNU nano is designed to be a free replacement for the Pico text editor, part of the Pine email suite from <a href="http://www.washington.edu/pine/">The University of Washington</a>. It aims to "emulate Pico as closely as possible and perhaps include extra functionality".</p></blockquote>
-<h2><a name="1.4"></a>1.4. What is the history behind nano?</h2>
-<blockquote><p>Funny you should ask!</p>
- <p><b>In the beginning...</b></p>
- <p>For years Pine was THE program used to read email on a Unix system. The Pico text editor is the portion of the program one would use to compose his or her mail messages. Many beginners to Unix flocked to Pico and Pine because of their well organized, easy to use interfaces. With the proliferation of GNU/Linux in the mid to late 90's, many University students became intimately familiar with the strengths (and weaknesses) of Pine and Pico.</p>
- <p><b>Then came Debian...</b></p>
- <p>The <a href="http://www.debian.org/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but they were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>
- <p><b>The event...</b></p>
- <p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
- <p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help menu, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is today.</p>
- <p>In February 2001, nano was declared an official GNU program by Richard Stallman. Nano also reached its first production release on March 22, 2001.</p></blockquote>
-<h2><a name="1.5"></a>1.5. Why the name change from TIP?</h2>
-<blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program "establishes a full duplex terminal connection to a remote host", and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>
-<h2><a name="1.6"></a>1.6. What is the current version of nano?</h2>
-<blockquote><p>The current version of nano *should* be 1.2.2. Of course you should always check the nano homepage to see what the latest and greatest version is.</p></blockquote>
-<h2><a name="1.7"></a>1.7. I want to read the man page without having to download the program!</h2>

-<blockquote><p>For the 'bleeding edge' current version of nano, you can use CVS to download the current source code. <b>Note:</b> believe it or not, by downloading code that has not yet stabilized into an official release, there could quite possibly be bugs, in fact the code may not even compile!

-<h1><a name="3"></a>3. Installation and Configuration</h1>
-<h2><a name="3.1"></a>3.1. How do install the RPM or DEB package?</h2>
-<blockquote><p>It's simple really! As root, type <b>rpm -Uvh nano-x.y.z-1.i386.rpm</b> if you have a RedHat-ish system or <b>dpkg -i nano_x.y.z-1.deb</b> if you have a Debian-ish system, where <b>x.y.z</b> is the release of nano. There are other programs to install packages, and if you wish to use those, knock yourself out.</p></blockquote>
-<h2><a name="3.2"></a>3.2. Compiling from source: WHAT THE HECK DO I DO NOW?</h2>
-<blockquote><p>Okay, take a deep breath, this really isn't hard. Unpack the nano source with a command like:</p>
- <p><b>tar -zxvf nano-x.y.z.tar.gz</b></p>
- <p>If you get error messages about the -z option, try this:</p>
- <p><b>gzip -dc nano-x.y.z.tar.gz | tar xvf -</b></p>
- <p>(again, where x.y.z is the version number in question). Then you need to run configure with any options you might want (if any).</p>
- <p>The average case is this:</p>
- <p><b>cd nano-x.y.z/</b><br>
- <b>./configure</b><br>
- <b>make</b><br>
- <b>make install</b> (as root, of course)</p></blockquote>
-<h2><a name="3.3"></a>3.3. Why does everything go into /usr/local?</h2>
-<blockquote><p>Well, that's what the <b>configure</b> script defaults to. If you wish to change this, simply do this:</p>
- <p><b>./configure --prefix=/usr</b></p>
- <p>to put nano into /usr/bin when you run <b>make install</b>.</p></blockquote>
-<h2><a name="3.4"></a>3.4. I get errors about 'bindtextdomain', 'gettext' and/or 'gettextdomain'. What can I do about it?</h2>
-<blockquote><p>Try doing a <b>./configure --with-included-gettext</b> and see if that solves your problem. You may need to do a <b>make clean; make</b> to get it to work fully.</p></blockquote>
-<h2><a name="3.5"></a>3.5. Nano should automatically run strip on the binary when installing it!</h2>
-<blockquote><p>Actually, it does, but you have to use <b>make install-strip</b>. The default make install does not, and will not, run strip automatically.</p></blockquote>
-<h2><a name="3.6"></a>3.6. How can I make the executable smaller? This is too bloated!</h2>
-<blockquote><p>Actually, there are several parts of the editor that can be disabled. You can pass arguments to the <b>configure</b> script that disable certain features. Here's a brief list:</p>
- <pre>
- <b>--disable-tabcomp</b> Disables tab completion code for a smaller binary
- <b>--disable-justify</b> Disable justify/unjustify function
- <b>--disable-speller</b> Disables spell checker function
- <b>--disable-help</b> Disables help function (^G)
- <b>--disable-browser</b> Disables mini file browser
- <b>--disable-wrapping</b> Disables all wrapping of text (and -w flag)
- <b>--disable-mouse</b> Disables mouse support (and -m flag)
- <b>--disable-operatingdir</b> Disable setting of operating directory</pre>
- <p>There's also the <b>--enable-tiny</b> option which disables everything above, as well as some larger chunks of the program (like the marker code that you use Control-^ to select with). Also, if you know you aren't going to be using other languages you can use <b>--disable-nls</b> to disable internationalization and save a few K to a few dozen K depending on if you have locale support on your system. And finally there's always good old <b>strip</b> to strip all debugging code and code that exists in libraries on your system.</p>
- <p>If, on the other hand, you can't live without bells and whistles, you could try:</p>
- <pre>
- <b>--enable-extra</b> Enable extra functions, including easter eggs
- <b>--enable-nanorc</b> Enable use of .nanorc file
- <b>--enable-color</b> Enables color and syntax highlighting
- <b>--enable-multibuffer</b> Enables having multiple file buffers open
- <b>--enable-all</b> Enables all of the above features</pre></blockquote>
-<h2><a name="3.7"></a>3.7. Tell me more about this multibuffer stuff!</h2>
-<blockquote><p>To use multiple file buffers, you must be using nano 1.1.12 or newer, and you must have configured nano with <b>--enable-multibuffer</b> or <b>--enable-extra</b> (use nano -V to check). Then when you want to enable inserting a file into its own buffer instead of into the current file, just hit <b>Meta-F</b>, then insert the file as normal with <b>^R</b>. If you always want files to be loaded into their own buffers, use the <b>--multibuffer</b> or <b>-F</b> flag when you invoke nano. </p>
- <p>You can move between the buffers you have open with the <b>Meta-<</b> and <b>Meta-></b> keys, or more easily with <b>Meta-,</b> and <b>Meta-.</b> (clear as mud, right? =-). When you have more than one file buffer open, the ^X shortcut will say "Close", instead of the normal "Exit" when only one buffer is open.</p></blockquote>
-<h2><a name="3.8"></a>3.8. How do I make a .nanorc file that nano will read when I start it?</h2>
-<blockquote>It's not hard at all! But, your version of nano must have been compiled with <b>--enable-nanorc</b>, and again must be version 1.1.12 or newer (use nano -V to check your version and compiled features). Then simply copy the <b>nanorc.sample</b> that came with the nano source or your nano package (most likely in /usr/doc/nano) to .nanorc in your home directory. If you didn't get one, the syntax is simple. Flags are turned on and off by using the word <b>set</b> and the getopt_long flag for the feature, for example "set pico" or "set nowrap".</blockquote>

You are welcome to submit it to the <a href="mailto:nano-devel@gnu.org">nano-devel</a> list or to <a href="mailto:nano@nano-editor.org">nano@nano-editor.org</a>.</p></blockquote>
-<h2><a name="4.3"></a>4.3. Nano crashes when I resize my window. How can I fix that?</h2>
-<blockquote><p>Older versions of nano had this problem, please upgrade to a newer version (at least 0.9.9 would be great, 0.9.12 is recommended).</p></blockquote>
-<h2><a name="4.4"></a>4.4. [version 1.1.12 and earlier] Why does nano show ^\ in the shortcut list instead of ^J?</h2>
-<blockquote><p>The help (^G) and justify (^J) function were among the last to be written. To show the improvements that nano had over Pico (go to line # and replace), ^_ and ^\ were put on the shortcut list. Later, ^G came back in place of ^_ as it proved to be very valuable for new Unix users. If you use the <b>-p</b> option to nano (or hit Meta-P) you will get the same shortcuts at the bottom as Pico.</p></blockquote>
-<a name="4.5"></a>
-<h2><a name="4.5a"></a>4.5a. [version 1.1.12 and earlier] When I type in a search string, the string I last searched for is already in front of my cursor! What happened?!</h2>
-<blockquote><p>In nano version 0.9.20, the default is to have a completely consistent user interface across all user input functions. This means that regardless of whether you're being asked for a filename to insert or write, or a string to search for, the previous value is already inserted before the cursor. If you prefer the old behavior, use the Pico emulation mode (-p or --pico) or just hit Meta-P while in nano (see the ^G help text for more details).</p></blockquote>
-<h2><a name="4.5b"></a>4.5b. [version 1.2.2 and later] Hey, the search string behavior has reverted, it's now like Pico, what happened to the consistency?</h2>
-<blockquote><p>It was decided that consistency was nice, but people are used to Pico's inconsistent behavior. Also, in version 1.1.99pre1, search and replace history was introduced. If you wish to edit your previous search/replace entry (or any previous entry), you can do so by hitting the up arrow to cycle through your history. This method allows the best of both worlds: You don't need to erase the previous string if you want to enter a new one, but you can with one keystroke recall previous entries for editing. Therefore there is now no "Pico mode", nano is and has always been a Pico <b>clone</b>, and clones by default should be compatible.</p></blockquote>
-<h2><a name="4.6"></a>4.6. I get the message "NumLock glitch detected. Keypad will malfunction with NumLock off." What gives?</h2>
-<blockquote><p>Nano (and actually almost all console editors) has issues when cycling the NumLock key in certain X terminals (rxvt, aterm, wterm, etc...). When you switch NumLock from on to off, you put the terminal into an "application mode" that changes what sequences are sent by the keypad. These sequences vary sufficiently from terminal to terminal that it is nearly impossible to work around them from within nano.</p>
- <p>In a nutshell, if you want to be able to use the keypad with the arrow and page up/down functionality, you have to exit nano and reset your terminal (presumably with "reset" or "stty sane" or similar) and then run nano again with NumLock off. If you know an easier way to restore "normal mode", please mail <a href="mailto:nano@nano-editor.org">nano@nano-editor.org</a>.</p></blockquote>
-<h2><a name="4.7"></a>4.7. How do I make nano my default editor (in Pine, mutt, etc.)?</h2>
-<blockquote><p>You need to make nano your $EDITOR. If you want this to be saved, you should put a line like this in your <b>.bashrc</b> if you use bash (or <b>.zshrc</b> if you believe in zsh):</p>
- <p><b>export EDITOR=/usr/local/bin/nano</b></p>
- <p>or if you use tcsh put this in your <b>.cshrc</b> file:</p>
- <p><b>setenv EDITOR /usr/local/bin/nano</b></p>
- <p>Change /usr/local/bin/nano to wherever nano is installed on your system. Type "which nano" to find out. This will not take effect until the next time you login. So log out and back in again.</p>
- <p>Then on top that if you use Pine you must go into setup (type <b>S</b> at the main menu), then configure (type <b>C</b>). Hit enter on the lines that say:</p>
- <p><b>[ ] enable-alternate-editor-cmd</b><br>
- <b>[ ] enable-alternate-editor-implicitly</b></p>
- <p>Then exit (<b>E</b>) and select Yes (<b>Y</b>).</p>
- <p>Mutt users should see an effect immediately the next time you log in, no further configuration is needed. However, if you want to let people know you use nano to compose your email messages, you can put a line like this in your <b>.muttrc</b>:</p>
- <p><b>my_hdr X-Composer: nano x.y.z</b></p>
- <p>Again, replace x.y.z with the version of nano you use.</p></blockquote>
-<h2><a name="4.8"></a>4.8. I've compiled nano with color support, but I don't see any color when I run it!</h2>
-<blockquote><p>If you want nano to actually use color, you have to specify the color configurations you want it to use in your .nanorc. Some example configurations are in the <b>nanorc.sample</b> that comes with the nano source or your nano package. See Section <a href="#3.8">3.8</a>.</p></blockquote>

-<h1><a name="5"></a>5. Internationalization</h1>
-<h2><a name="5.1"></a>5.1. There's no translation for my language!</h2>
-<blockquote><p>On June of 2001, GNU nano entered the <a href="http://www.iro.umontreal.ca/contrib/po/HTML/">Free Translation Project</a> and since then, translations should be managed from there.</p>
- <p>If there isn't a translation for your language, you could ask <a href="http://www.iro.umontreal.ca/contrib/po/HTML/teams.html">your language team</a> to translate nano, or better still, join your team and do it yourself. Joining a team is easy. You just need to ask the <a href="mailto:translation@iro.umontreal.ca">TP coordinator</a> to add you to your team, and send a <a href="http://www.iro.umontreal.ca/contrib/po/HTML/disclaim.html">translation disclaimer to the FSF</a> (this is necessary as nano is an official GNU package, but it does <b>not</b> mean that you transfer the rights of your work to the FSF, it's just so the FSF can legally manage them).</p>
- <p>In any case, translating nano is very easy. Just grab the <b>nano.pot</b> file from the latest and greatest nano distribution (it's in the <b>po/</b> directory) and translate each line into your native language on the <b>msgstr</b> line. When you're done, you should send it to the TP's central po repository.</p></blockquote>
-<h2><a name="5.2"></a>5.2. I don't like the translation for <x> in my language. How can I fix it?</h2>
-<blockquote><p>The best way would probably be to e-mail the person listed in the <code>Last-Translator:</code> field in the <b><your_language>.po</b> file with your suggested corrections and they can make the changes reach the nano-devel list.</p></blockquote>

-<h1><a name="6"></a>6. Advocacy and Licensing</h1>
-<h2><a name="6.1"></a>6.1. Why should I use nano instead of Pico?</h2>
-<blockquote><p>There are many reasons to use nano instead of Pico, a more complete list can be found at the <a href="http://www.nano-editor.org/">nano homepage</a>.</p></blockquote>
-<h2><a name="6.2"></a>6.2. Why should I use Pico instead of nano?</h2>
-<blockquote><p>Again, check out the <a href="http://www.nano-editor.org/">nano homepage</a> for a good summary of reasons. It really is a matter of personal preference as to which editor you should use. If you're the type of person who likes using the original version of a program, then Pico is the editor for you. If you're looking for a few more features and a 'better' license as far as adding your own changes (sacrificing mailer integration with Pine), nano is the way to go.</p></blockquote>
-<h2><a name="6.3"></a>6.3. What is so bad about the Pine license?</h2>
-<blockquote><p>The U of W license for Pine and Pico is not considered truly Free Software according to both the Free Software Foundation and the <a href="http://www.debian.org/social_contract#guidelines">Debian Free Software Guidelines</a>. The main problem regards the limitations on distributing derived works: according to UW, you can distribute their software, and you can modify it, but you can not do both, i.e. distribute modified binaries.</p></blockquote>
-<h2><a name="6.4"></a>6.4. Okay, well what mail program should I use then?</h2>
-<blockquote><p>If you are looking to use a Free Software program similar to Pine and emacs is not your thing, you should definitely take a look at <a href="http://www.mutt.org/">mutt</a>. It is a full-screen, console based mail program that actually has a lot more flexibility than Pine, but has a keymap included in the distribution that allows you to use the same keystrokes as Pine would to send and receive mail. It's also licensed under the GPL.</p></blockquote>
-<h2><a name="6.5"></a>6.5. Why doesn't UW simply change their license?</h2>
-<blockquote><p>You're really not asking the right person here. I (Chris) waited a long time to see if UW would change their license because of the amount of high quality software being released and developed under the GPL without being taken advantage of by malicious corporate entities or other baddies, but no such luck so far.</p></blockquote>
-<h2><a name="6.6"></a>6.6. What if tomorrow UW changes the license to be truly Free Software?</h2>
-<blockquote><p>Honestly nothing would make me happier than to see that happen. Nano would continue to be developed independently until such time as Pico had all the features nano did or the projects merged. That just does not seem very likely given that there has been no sign of any changes in the past few years in a positive direction.</p></blockquote>
-<hr width="100%">
-<h1><a name="7"></a>7. Miscellaneous</h1>
-<h2><a name="7.1"></a>7.1. Nano related mailing lists.</h2>
-<blockquote><p>There are three mailing lists for nano hosted at <a href="http://savannah.gnu.org/">Savannah</a>, info-nano, help-nano and nano-devel. Info-nano is a very low traffic list where new versions of nano are announced (surprise!) Help-nano is for getting help with the editor without needing to hear all of the development issues surrounding it. Nano-devel is a normally low, sometimes high traffic list for discussing the present and future development of nano. Here are links to where you can sign up for a given list:</p>
- <p>info-nano - <a href="http://mail.gnu.org/mailman/listinfo/info-nano/">http://mail.gnu.org/mailman/listinfo/info-nano/</a><br>

-<h2><a name="7.2"></a>7.2. I want to send the development team a big load of cash (or just a thank you).</h2>
-<blockquote><p>That's fine. Send it <a href="mailto:nano-devel@gnu.org">our way</a>! Better yet, fix a <a href="http://www.nano-editor.org/dist/v1.2/BUGS">bug</a> in the program or implement a <a href="http://www.nano-editor.org/dist/v1.2/TODO">cool feature</a> and send us that instead (though cash is fine too).</p></blockquote>
-<h2><a name="7.3"></a>7.3. How do I submit a patch?</h2>
-<blockquote><p>See Section <a href="#7.2">7.2</a>.</p></blockquote>
-<h2><a name="7.4"></a>7.4. How do I join the development team?</h2>
-<blockquote><p>The easiest way is to consistently send in good patches that add some needed functionality, fix a bug or two and/or make the program more optimized/efficient. Then ask nicely and you will probably be added to the Savannah development list and be given CVS write access after awhile. There is a lot of responsibility that goes along with being a team member, so don't think it's just something to add to your resume.</p></blockquote>
-<h2><a name="7.5"></a>7.5. Can I have CVS write access?</h2>

-.SH NAME
-nano \- Nano's ANOther editor, an enhanced free Pico clone
-
-.SH SYNOPSIS
-.B nano
-.I [\+LINE]\ [options]\ [file]
-.br
-
-.SH DESCRIPTION
-This manual page documents briefly the \fBnano\fP command.
-.PP
-.\" TeX users may be more comfortable with the \fB<whatever>\fP and
-.\" \fI<whatever>\fP escape sequences to invoke bold face and italics,
-.\" respectively.
-\fBnano\fP is a small, free and friendly editor which aims to replace
-Pico, the default editor included in the non-free Pine package. Rather
-than just copying Pico's look and feel, \fBnano\fP also implements some
-missing (or disabled by default) features in Pico, such as "search and
-replace" and "go to line number".
-
-.SH OPTIONS
-.TP
-.B \+\fILINE\fP
-Places cursor at \fILINE\fP on startup.
-.TP
-.B \-B (\-\-backup)
-When saving a file, back up the previous version of it to the current
-filename suffixed with a ~.
-.TP
-.B \-D (\-\-dos)
-Write file in DOS format.
-.TP
-.B \-F (\-\-multibuffer)
-Enable multiple file buffers, if available.
-.TP
-.B \-H (\-\-historylog)
-Log search and replace strings to
-.I ~/.nano_history
-so they may be stored for later editing, if nanorc support is
-configured.
-.TP
-.B \-I (\-\-ignorercfiles)
-Don't look at
-.I SYSCONFDIR/nanorc
-or
-.IR ~/.nanorc ,
-if nanorc support is available.
-.TP
-.B \-M (\-\-mac)
-Write file in Mac format.
-.TP
-.B \-N (\-\-noconvert)
-Disable automatic conversion of files from DOS/Mac format.
-.TP
-.B \-Q \fIstr\fP (\-\-quotestr=\fIstr\fP)
-Set the quoting string for justifying. The default is
-"^([\ \\t]*[|>:}#])+" if regular expression support is available, or
-">\ " otherwise.
-.TP
-.B \-R (\-\-regexp)
-Enable regular expression matching for search strings, as well as
-\\n subexpression replacement for replace strings, if available.
-.TP
-.B \-S (\-\-smooth)
-Enable smooth scrolling. Text will scroll line-by-line, instead of the
-usual chunk-by-chunk behavior.
-.TP
-.B \-T \fInum\fP (\-\-tabsize=\fInum\fP)
-Set the size (width) of a tab.
-.TP
-.B \-V (\-\-version)
-Show the current version number and author.
-.TP
-.B \-Y \fIstr\fP (\-\-syntax=\fIstr\fP)
-Specify a specific syntax highlighting from the
-.I .nanorc
-to use, if available.
-.TP
-.B \-c (\-\-const)
-Constantly show the cursor position.
-.TP
-.B \-d (\-\-rebinddelete)
-Interpret the Delete key differently so that both Backspace and Delete
-work properly. You should only need to use this option if Backspace
-acts like Delete on your system.
-.TP
-.B \-h (\-\-help)
-Display a summary of command line options.
-.TP
-.B \-i (\-\-autoindent)
-Indent new lines to the previous line's indentation. Useful when editing
-source code.
-.TP
-.B \-k (\-\-cut)
-Enable cut from cursor to end of line with ^K.
-.TP
-.B \-l (\-\-nofollow)
-If the file being edited is a symbolic link, replace the link with
-a new file, do not follow it. Good for editing files in
-.IR /tmp ,
-perhaps?
-.TP
-.B \-m (\-\-mouse)
-Enable mouse support (if available for your system).
-.TP
-.B \-o \fIdir\fP (\-\-operatingdir=\fIdir\fP)
-Set operating directory. Makes nano set up something similar to a
-chroot.
-.TP
-.B \-p (\-\-preserve)
-Preserve the XON and XOFF sequences (^Q and ^S) so they will be caught
-by the terminal.
-.TP
-.B \-r \fIcols\fP (\-\-fill=\fIcols\fP)
-Wrap lines at column \fIcols\fP. By default, this is the width of the
-screen, less eight. If this value is negative, wrapping will occur at
-\fIcols\fP columns from the right of the screen, allowing the wrap point
-to vary along with the screen width if resized.
-.TP
-.B \-s \fIprog\fP (\-\-speller=\fIprog\fP)
-Enable alternative spell checker command.
-.TP
-.B \-t (\-\-tempfile)
-Always save changed buffer without prompting. Same as Pico -t option.
-.TP
-.B \-v (\-\-view)
-View file (read only) mode.
-.TP
-.B \-w (\-\-nowrap)
-Disable wrapping of long lines.
-.TP
-.B \-x (\-\-nohelp)
-Disable help screen at bottom of editor.
-.TP
-.B \-z (\-\-suspend)
-Enable suspend ability.
-.TP
-.B \-a, \-b, \-e, \-f, \-g, \-j
-Ignored, for compatibility with Pico.
-
-.SH INITIALIZATION FILE
-\fBnano\fP will read initialization files in the following order:
-.IR SYSCONFDIR/nanorc ,
-then
-.IR ~/.nanorc .
-Please see
-.BR nanorc (5)
-and the example file \fBnanorc.sample\fP which should be provided with
-\fBnano\fP.
-
-.SH NOTES
-\fBnano\fP will try to dump the buffer into an emergency file in some
-cases. Mainly, this will happen if \fBnano\fP receives a SIGHUP or
-SIGTERM or runs out of memory, when it will write the buffer into a file
-named
-.I nano.save
-if the buffer didn't have a name already, or will add a ".save" suffix
-to the current filename. If an emergency file with that name already
-exists in the current directory, ".save" and a number (e.g. ".save.1")
-will be suffixed to the current filename in order to make it unique. In
-multibuffer mode, \fBnano\fP will write all the open buffers to the
-respective emergency files.
-
-.SH BUGS
-Please send any comments or bug reports to
-.BR nano@nano-editor.org .

-.BR nano-devel@gnu.org .

-The original goal for @code{nano} was a complete bug-for-bug compatible
-emulation of Pico, but nano's main goal is to be as compatible as
-possible while offering a superset of Pico's functionality. Also see
-@xref{Pico Compatibility}, for other differences.

-Write file in Mac format.
-
-@item -N, --noconvert
-Do not convert files from DOS/Mac format.
-
-@item -Q [str], --quotestr [str]
-Set the quoting string for justifying. The default is
-
-@quotation
-@code{^([ \t]*[|>:@}#])+}
-@end quotation
-
-if regular expression support is available, or ``> '' otherwise. Note
-that @code{\t} above stands for a literal Tab character.

-@item -Y, --syntax=[str]
-Specify a specific syntax highlighting from the .nanorc to use, if
-available.
-
-@item -c, --const
-Constantly display the cursor position and line number on the statusbar.
-
-@item -d, --rebinddelete
-Interpret the Delete key differently so that both Backspace and Delete
-work properly. You should only need to use this option if Backspace
-acts like Delete on your system.
-
-@item -h, --help
-Print the usage and exit.
-
-@item -i, --autoindent
-Automatically indent new lines to the same number of spaces and tabs as
-the previous line.
-
-@item -k, --cut
-Makes ^K cut from the current cursor position to the end of the current
-line.

-@item -l, --nofollow
-When writing files, if the given file is a symbolic link it is removed
-and a new file is created.
-
-@item -m, --mouse
-Enables the use of the mouse to select text (currently only useful for
-running under the X window system).
-
-@item -o [dir], --operatingdir=[dir]
-Set operating directory. Makes @code{nano} set up something similar to
-a chroot.
-
-@item -p, --preserve
-Preserve the ^Q (XON) and ^S (XOFF) sequences so data being sent to the
-editor can be can be stopped and started.
-
-@item -r [#cols], --fill=[#cols].
-Wrap lines at column #cols. By default this is the width of the screen,
-less eight. If this value is negative, wrapping will occur at #cols
-from the right of the screen, allowing it to vary along with the screen
-width if the screen is resized.
-
-@item -s [prog], --speller=[prog]
-Invoke [prog] as the spell checker. By default, @code{nano} uses its
-own interactive spell checker that requires the @code{spell} program be
-installed on your system.
-
-@item -t, --tempfile

-exiting, assume yes. This is most useful when using @code{nano} as the
-composer of a mailer program.
-
-@anchor{Expert Mode}
-@item -x, --nohelp
-In Expert Mode, the Shortcut Lists will not appear at the bottom of the
-screen. This affects the location of the statusbar as well, as in
-Expert Mode it is located at the very bottom of the editor.
-
-Note: When accessing the help system, Expert Mode is temporarily
-disabled to display the help system navigation keys.
-
-@item -v, --view
-Do not allow the contents of the file to be altered. Note that this
-flag should NOT be used in place of correct file permissions to
-implement a read-only file.
-
-@item -w, --nowrap
-Do not wrap long lines at any length. This option overrides any value
-for -r.
-
-@item -z, --suspend
-Enable suspend ability of @code{nano} using the system's suspend
-keystroke (usually ^Z).
-
-@item -a, -b, -e, -f, -g, -j

-@section Entering Text
-
-All key sequences in @code{nano} are entered using the keyboard.
-@code{nano} is a ``modeless'' editor. All keys with the exception of
-Control and Meta key sequences will enter text into the file being
-edited.
-
-@node Special Functions, The Titlebar, Entering Text, Editor Basics
-@section Special Functions
-
-Special functions use the Control key (displayed in the help and
-shortcut lists as ^), the Meta key (displayed as M), or the Esc key.
-
-@itemize @bullet
-@item
-Control key sequences are entered by holding down the Control key and
-pressing the desired key, or by pressing the Esc key twice and pressing
-the desired key.
-@item
-Pressing Esc twice and then typing a three-digit number from 000 to 255
-will enter the character with the corresponding ASCII code.
-@item
-Meta key sequences can be entered in a number of possible ways: Pressing
-the Escape key, then releasing it and pressing the desired key, or
-holding down the Alt key while pressing the desired key. This varies
-from keyboard to keyboard, and certain commercial operating systems
-``swallow'' the Alt key so that it never reaches the application. If
-your operating system does this, you should use the Escape key to
-generate Meta key sequences.

-@section The Titlebar
-
-The titlebar is the line displayed at the top of the editor. There are
-three sections: left, center and right. The section on the left
-displays the version of @code{nano} being used. The center section
-displays the current file name, or ``New Buffer'' if the file has not
-yet been named. The section on the right will display ``Modified'' if
-the file has been modified since it was last saved or opened.
-
-Special modes: When @code{nano} is in ``File browser'' mode, the center
-section will display the current directory instead of the filename.

-@section The Statusbar
-
-The statusbar is located three lines from the bottom of the screen (or
-the bottom line in Expert Mode. @xref{Expert Mode}, for more info).
-
-The Statusbar shows important and informational messages. Any error
-messages that occur from using the editor will appear on the statusbar.
-Any questions that are asked of the user will be asked on the statusbar,
-and any user input (search strings, file names, etc) will be input on
-the statusbar.

-@chapter Online Help
-
-The online help system in @code{nano} is available by pressing ^G.
-It is fairly self explanatory, documenting the various parts of the
-editor and available keystrokes. Navigation is via the ^Y (Page Up)
-and ^V (Page Down) keys. ^X exits the help system.
-
-
-@node Feature Toggles, The File Browser, Online Help, Top
-@chapter Feature Toggles
-
-Toggles allow you to change certain aspects of the editor that
-would normally be done via command line flags. They are invoked via
-certain Meta key sequences. @xref{Special Functions}, for more info.
-The following global toggles are available:
-
-@table @code
-
-@item Backup File Toggle (Meta-B)
-toggles the -B (@code{--backup}) command line flag.
-
-@item DOS Format Toggle (Meta-D)
-toggles the -D (@code{--dos}) command line flag.
-
-@item Multiple Files Toggle (Meta-F)
-toggles the -F (@code{--multibuffer}) command line flag.
-
-@item AutoIndent Toggle (Meta-I)
-toggles the -i (@code{--autoindent}) command line flag.
-
-@item Cut To End Toggle (Meta-K)
-toggles the -k (@code{--cut}) command line flag.
-
-@item Mouse Toggle (Meta-M)
-toggles the -m (@code{--mouse}) command line flag.
-
-@item Mac Format Toggle (Meta-O)
-toggles the -M (@code{--mac}) command line flag.
-
-@item Smooth Scrolling Toggle (Meta-S)
-toggles the -S (@code{--smooth}) command line flag.
-
-@item AutoWrap Toggle (Meta-W)
-toggles the -w (@code{--nowrap}) command line flag.
-
-@item Expert/Nohelp Toggle (Meta-X)
-toggles the -x (@code{--nohelp}) command line flag.
-
-@item Suspend Toggle (Meta-Z)
-toggles the -z (@code{--suspend}) command line flag.
-
-@item Open Previous File Toggle (Meta-<)
-changes buffer to previously loaded file.

-@node The File Browser, Pico Compatibility, Feature Toggles, Top
-@chapter The File Browser
-
-When reading or writing files, pressing ^T will invoke the file browser.
-Here, one can navigate directories in a graphical manner in order to
-find the desired file.
-
-Basic movement in the file browser is accomplished with the arrow keys
-and page up/down. The behavior of the enter (or `s') key varies by what
-is currently selected. If the currently selected object is a directory,
-the file browser will enter and display the contents of the directory.
-If the object is a file, this filename and path are copied to the
-statusbar and the file browser is exited.
-
-@node Pico Compatibility, Building and Configure Options, The File Browser, Top
-@chapter Pico Compatibility
-
-@code{nano} attempts to emulate Pico as closely as possible, but there
-are certain differences between the editors:
-
-@table @code
-@item Search and Replace History
-As of version 1.2.2 of @code{nano}, text entered as search or replace
-strings will be stored and can be accessed with the up/down arrow keys.
-Previously, @code{nano} offered a more consistent, but incompatible with
-Pico, method for entering search and replace strings. In the old
-method, previous entries would be displayed by default as editable text
-in front of the cursor, as opposed to being bracketed and uneditable as
-it is in Pico. The old behavior could be made compatible with Pico via
-the @code{-p} flag, but recent versions of Pico use the @code{-p} flag
-to preserve the XON and XOFF sequences within the editor. Since with
-the new method search and replace strings can still be edited by simply
-hitting the up arrow key once, the old method was removed completely.
-
-
-@item Writing or Appending Selected Text to Files
-Text selected using the Control-Caret (^^) key can be written out or
-appended to a new or existing file using the Writeout key (^O).
-
-@item Toggles
-Many options which alter the functionality of the program can be
-"toggled" on or off using Meta key sequences, meaning the program does
-not have to be restarted to turn a particular feature of the editor on
-or off. Please see the internal help function (^G) for a list of what
-functions can be toggled for a particular version of @code{nano}. Also
-see @xref{Feature Toggles}, though this may be out of date.
-
-@item Cursor Position Display
-The output of the "Display Cursor Position" in @code{nano} displays
-the given column position, as well as the row and total character
-position of the cursor.
-
-@item Interactive Replace and Spell Checker
-It is worth noting that the @code{nano} replace function is interactive,
-i.e, it does not stop after one search string is found and automatically
-replace it. The @code{nano} implementation will stop at each search
-string found and query whether to replace this instance or not. The
-internal spell checker operates similarly. Note that these is no way to
-force these functions to behave in the Pico fashion. As of version
-1.2.2, misspelled words are sorted and trimmed for uniqueness in the
-internal spell checker such that the words 'apple' and 'Apple' will be
-prompted for correction separately.
-@end table
-
-@node Building and Configure Options, , Pico Compatibility, Top
-@chapter Building and Configure Options
-
-Building @code{nano} from source is fairly straightforward if you are
-familiar with compiling programs with autoconf support:
-
-@itemize @bullet
-@item tar xvfz nano-x.y.z.tar.gz (where x.y.z is the version of nano)
-@item cd nano-x.y.z/
-@item ./configure
-@item make
-@item make install
-@end itemize
-
-if you are looking to optimize @code{nano} for size, you may want to
-consider the following command line options:
-
-
-@table @code
-
-@item --disable-tabcomp
-Disable the tab completion code when reading or writing files.
-
-@item --disable-justify
-Disable the justify (^J)/unjustify (^U) functions in the editor.
-
-@item --disable-speller
-Disable spell checker ability.
-
-@item --disable-help
-Disable the help function (^G). Disabling this option makes the binary
-much smaller, but makes it difficult for new users to learn more than
-very basic things about using the editor.
-
-@item --disable-browser
-Disable the mini file browser (^T) when reading or writing files.
-
-@item --disable-mouse
-Disable all mouse functionality. This also disables the -m command line
-flag, which enables the mouse functions.
-
-@item --disable-operatingdir
-Disable setting the operating directory. This also disables the -o
-command line flag.
-
-@item --enable-tiny
-This option disables all the above. It also disables some of the larger
-internals of the editor, like the marker code (^^) and the cut to line
-(-k) option, which depends on the marker code to work properly. It also
-disables the function toggles.
-
-@item --disable-wrapping
-Disable all word wrapping in the editor. This also eliminates the -w
-command line flag, as nonwrapping is then the default behavior.
-
-@item --disable-nls
-Disables Native Language support. This will make the available GNU
-@code{nano} translations unusable.
-
-@item --with-slang
-Compiling GNU @code{nano} with Slang is supported, and will make the
-binary notably smaller than if compiled with ncurses or other curses
-libraries.

-missing (or disabled by default) features in Pico, such as "search and
-replace" and "go to line number".
-.PP
-The \fInanorc\fP file contains the default settings for \fBnano\fP.
-During startup, \fBnano\fP will first read its system-wide settings from
-.IR SYSCONFDIR/nanorc ,
-and then user-specific settings from
-.IR ~/.nanorc .
-
-.SH OPTIONS
-The configuration file accepts a series of "set" and "unset" commands,
-which can be used to configure nano on startup without using the
-command-line options. Additionally, the "syntax" and "color" keywords
-are used to define syntax highlighting rules for different text
-patterns. GNU nano will read one command per line.
-
-Options in rcfiles take precedence over nano's defaults, and command
-line options override rcfile settings.
-
-Options are unset by default, except for options that take an argument.
-
-The supported commands and arguments are:
-
-.TP 3
-\fBset/unset autoindent\fP
-Use auto-indentation.
-.TP
-\fBset/unset backup\fP
-Create backup files in
-.IR filename~ .
-.TP
-\fBset/unset const\fP
-Constantly display the cursor position in the status bar.
-.TP
-\fBset/unset cut\fP
-Use cut to end of line with ^K by default.
-.TP
-\fBset fill \fIn\fP\fP
-Wrap lines at column number \fIn\fP. If \fIn\fP is 0 or less, the line
-length will be the screen width less \fIn\fP. The default value is -8.
-.TP
-\fBset/unset historylog\fP
-Enable
-.I ~/.nano_history
-for saving and reading search/replace strings.
-.TP
-\fBset/unset multibuffer\fP
-Allow inserting files into their own buffers.
-.TP
-\fBset/unset noconvert\fP
-Don't convert files from DOS/Mac format.
-.TP
-\fBset/unset nofollow\fP
-Don't follow symlinks when writing files.
-.TP
-\fBset/unset nohelp\fP
-Don't display the help lists at the bottom of the screen.
-.TP
-\fBset/unset nowrap\fP
-Don't wrap text at all.
-.TP
-\fBset operatingdir "\fIdirectory\fP"\fP
-\fBnano\fP will only read and write files inside \fIdirectory\fP and its
-subdirectories. Also, the current directory is changed to here, so
-files are inserted from this dir. By default the operating directory
-feature is turned off.
-.TP
-\fBset/unset preserve\fP
-Preserve the XON and XOFF keys (^Q and ^S).
-.TP
-\fBset quotestr "\fIstring\fP"\fP
-The email-quote string, used to justify email-quoted paragraphs. This
-is an "extended regular expression" if your system supports them,
-otherwise a literal string. The default value is
-
- set quotestr "^([\ \\t]*[|>:}#])+"
-
-if you have regexps, otherwise set quotestr ">\ ". Note that '\\t'
-above stands for a literal Tab character.
-.TP
-\fBset/unset rebinddelete\fP
-Interpret the Delete key differently so that both Backspace and Delete
-work properly. You should only need to use this option if Backspace
-acts like Delete on your system.
-.TP
-\fBset/unset regexp\fP
-Do regular expression searches by default.
-.TP
-\fBset/unset smooth\fP
-Use smooth scrolling by default.
-.TP
-\fBset speller \fIspellprog\fP\fP
-Use spelling checker \fIspellprog\fP instead of the built-in one, which
-calls \fIspell\fP.
-.TP
-\fBset/unset suspend\fP
-Allow nano to be suspended with ^Z.
-.TP
-\fBset tabsize \fIn\fP\fP
-Use a tab size of \fIn\fP instead of the default (8); must be greater
-than 0.
-.TP
-\fBset/unset tempfile\fP
-Save automatically on exit, don't prompt.
-.TP
-\fBset/unset view\fP
-Disallow file modification.
-.TP
-.B syntax "\fIstr\fP" ["\fIfileregex\fP" ... ]
-Defines a syntax named \fIstr\fP which can be activated via the \fB-Y\fP
-flag, or will be automatically activated if the current filename matches
-\fIfileregex\fP. All following \fBcolor\fP statements will apply to
-\fIsyntax\fP until a new syntax is defined.
-.TP
-.B color \fIfgcolor\fP[,\fIbgcolor\fP] "\fIregex\fP" ...
-For the currently defined syntax, display all expressions matching
-\fIregex\fP with foreground color \fIfgcolor\fP and optional background
-color \fIbgcolor\fP. Legal colors for foreground and background color
-are: white, black, red, blue, green, yellow, magenta, and cyan. You may
-use the prefix "bright" to force a stronger color highlight. If your
-terminal supports transparency, not specifying a \fIbgcolor\fP tells
-\fBnano\fP to attempt to use a transparent background.
-.TP
-.B color \fIfgcolor\fP[,\fIbgcolor\fP] start="\fIsr\fP" end="\fIer\fP"
-Display expressions which start with \fIsr\fP and end with \fIer\fP
-with foreground color \fIfgcolor\fP and optional background color
-\fIbgcolor\fP. This allows syntax highlighting to span multiple lines.
-Note that all subsequent instances of \fIsr\fP after an initial \fIsr\fP
-is found will be highlighted until the first instance of \fIer\fP.

-## Sample initialization file for GNU nano
-## Please note that you must have configured nano with --enable-nanorc
-## for this file to be read! Also note that characters specially
-## interpreted by the shell should not be escaped here.
-##
-## To make sure a value is not enabled, use "unset <option>"
-##
-## For the options that take parameters, the default value is given.
-## Other options are unset by default.
-
-## Use auto-indentation
-# set autoindent
-
-## Backup files to filename~
-# set backup
-
-## Constantly display the cursor position in the status bar.
-# set const
-
-## Use cut to end of line with ^K by default
-# set cut
-
-## Set the line length for wrapping text and justifying paragraphs.
-## If fill is negative, the line length will be the screen width less
-## this number.
-##
-# set fill -8
-
-## Enable ~/.nano_history for saving and reading search/replace strings.
-# set historylog
-
-## Allow multiple file buffers (using ^R inserts into separate buffer).
-## You must have configured with --enable-multibuffer or --enable-extra
-## for this to work.
-##
-## set multibuffer
-
-## Don't convert files from DOS/Mac format
-# set noconvert
-
-## Don't follow symlinks when writing files
-# set nofollow
-
-## Don't display the help lists at the bottom of the screen
-# set nohelp
-
-## Don't wrap text at all
-# set nowrap
-
-## Set operating directory. nano will not read or write files outside
-## this directory and its subdirectories. Also, the current directory
-## is changed to here, so files are inserted from this dir. A blank
-## string means the operating directory feature is turned off.
-##
-# set operatingdir ""
-
-## Preserve the XON and XOFF keys (^Q and ^S)
-# set preserve
-
-## The email-quote string, used to justify email-quoted paragraphs.
-## This is an extended regular expression if your system supports them,
-## otherwise a literal string. Default:
-# set quotestr "^([ ]*[\|>:}#])+"
-## if you have regexps, otherwise:
-# set quotestr "> "
-## You can get old nano quoted-justify behavior via:
-# set quotestr "(> )+"
-
-## Fix Backspace if it acts like Delete
-# set rebinddelete
-
-## Do extended regular expression searches by default
-# set regexp
-
-## Use smooth scrolling as the default
-# set smooth
-
-## Use this spelling checker instead of the internal one. This option
-## does not properly have a default value.
-##
-# set speller "aspell -c"
-
-## Allow nano to be suspended with ^Z
-# set suspend
-
-## Use this tab size instead of the default; it must be greater than 0
-# set tabsize 8
-
-## Save automatically on exit, don't prompt
-# set tempfile
-
-## Disallow file modification, why would you want this in an rc file? ;)
-# set view
-
-## Color setup
-## Format:
-## syntax "short description" ["filename regex" ...]
-## color foreground,background "regex" ["regex"...]
-##
-## Legal colors: white, black, red, blue, green, yellow, magenta, cyan.
-## You may use the prefix "bright" to mean a stronger color highlight.
-##
-## To use multi-line regexes use the start="regex" end="regex" format.
-##
-## If your system supports transparency, not specifying a background
-## color will use a transparent color. If you don't want this, be sure
-## to set the background color to black or white.
-##

-# color brightyellow "\<(if|while|do|else|case|switch)\>"
-# color brightcyan "^ *# *(define|include|ifn?def|endif|elif|else|if)"

-## You will in general want your comments and strings to come last,
-## because syntax highlighting rules will be applied in the order they
-## are read in.
