docs: mention in the FAQ how to change the escape sequences of urxvt 

Replace an obsolete question that doesn't have a good answer: setting
TERM to vt100 is unlikely to make the more complicated keystrokes work,
which are the ones that are most likely not to work.

<h3><a name="4.2"></a>4.2. How can I make Ctrl+Shift+Left/Right select words on urxvt?</h3>
<blockquote><p>The urxvt terminal emulator produces non-standard escape sequences for the modified cursor keys. These deviant sequences are not listed in the terminfo database, which means that ncurses does not recognize them. The easiest way around this is to tell urxvt to produce xterm-compatible escape sequences for the relevant keystrokes. To achieve this, add the following lines to your ~/.Xresources file:</p>
<pre>
URxvt.iso14755_52: False
URxvt.keysym.C-S-Up: \033[1;6A
URxvt.keysym.C-S-Down: \033[1;6B
URxvt.keysym.C-S-Right: \033[1;6C
URxvt.keysym.C-S-Left: \033[1;6D
URxvt.keysym.M-Up: \033[1;3A
URxvt.keysym.M-Down: \033[1;3B
URxvt.keysym.M-Right: \033[1;3C
URxvt.keysym.M-Left: \033[1;3D
URxvt.keysym.M-Insert: \033[2;3~
URxvt.keysym.M-Delete: \033[3;3~
URxvt.keysym.M-Page_Up: \033[5;3~
URxvt.keysym.M-Page_Down: \033[6;3~</pre>
<p>Then run <b>xrdb ~/.Xresources</b> and restart your urxvt terminal. Now <b>Ctrl+Shift+Left</b> and <b>Ctrl+Shift+Right</b> will select words, <b>Alt+Up</b> and <b>Alt+Down</b> will scroll the text without moving the cursor, and several such things more.</p></blockquote>
<h3><a name="4.3"></a>4.3. Ack! My numeric keypad's keys don't work properly when NumLock is off! What can I do?</h3>
<blockquote><p>You can use the <b>-K</b> or <b>--rawsequences</b> option on the command line, or add the line <b>set rawsequences</b> to your .nanorc. However, nano's mouse support will be disabled if you do any of these things.</p></blockquote>
