<DL COMPACT>
<DT><CODE>$if</CODE>
<DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
editing mode, the terminal being used, or the application using
Readline.  The text of the test extends to the end of the line;
no characters are required to isolate it.
<P>

<DL COMPACT>
<DT><CODE>mode</CODE>
<DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
This may be used in conjunction
with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
Readline is starting out in <CODE>emacs</CODE> mode.
<P>

<DT><CODE>term</CODE>
<DD>The <CODE>term=</CODE> form may be used to include terminal-specific
key bindings, perhaps to bind the key sequences output by the
terminal's function keys.  The word on the right side of the
<SAMP>`='</SAMP> is tested against both the full name of the terminal and
the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
for instance.
<P>

<DT><CODE>application</CODE>
<DD>The <VAR>application</VAR> construct is used to include
application-specific settings.  Each program using the Readline
library sets the <VAR>application name</VAR>, and you can test for
a particular value. 
This could be used to bind key sequences to functions useful for
a specific program.  For instance, the following command adds a
key sequence that quotes the current or previous word in Bash:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
# Quote the current or previous word
"\C-xq": "\eb\"\ef\""
$endif
</pre></td></tr></table></DL>
<P>

<DT><CODE>$endif</CODE>
<DD>This command, as seen in the previous example, terminates an
<CODE>$if</CODE> command.
<P>

<DT><CODE>$else</CODE>
<DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
the test fails.
<P>

<DT><CODE>$include</CODE>
<DD>This directive takes a single filename as an argument and reads commands
and bindings from that file.
For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
<TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
</pre></td></tr></table></DL>
