   <p>You can move between the buffers you have open with the <b>Meta-&lt;</b> and <b>Meta-&gt;</b> keys, or more easily with <b>Meta-,</b> and <b>Meta-.</b> (clear as mud, right? =-).

 <h2><a name="3.8"></a>3.8. Tell me more about this verbatim input stuff!</h2>
 <blockquote><p>To use verbatim input, you must be using nano 1.3.1 or newer. When you want to insert a literal character into the file you're editing, such as a control character that nano usually treats as a command, first press <b>Meta-V</b>. (If you're not at a prompt, you'll get the message &quot;Verbatim input&quot;.) Then press the key(s) that generate the character you want.</p>
-  <p>Alternatively, you can press <b>Meta-V</b> and then type a three-digit ASCII code from 000 to 255, and the character with that ASCII code will be inserted instead.</p>
-  <p><b>NOTE:</b> Verbatim input doesn't work at prompts right now. This will be fixed soon.</p></blockquote>

 <h2><a name="3.9"></a>3.9. How do I make a .nanorc file that nano will read when I start it?</h2>
 <blockquote><p>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 &quot;set nowrap&quot; or &quot;set suspend&quot;.</p></blockquote>

 2004/11/05 - Fixed inaccuracy: Pico compatibility mode was made the default in nano 1.1.99pre1, not 1.2.2. Also added question about how to type F13-F16 on terminals lacking keys past F12 (suggested by Chris), question about how to select text for the clipboard in X terminals with nano's mouse support turned on (answer found by Joseph Birthisel), and misc. fixes and link updates.
