<p>Octave uses the GNU Readline library for command-line editing and
history features. Readline is very flexible and can be modified through
a configuration file of commands (See the GNU Readline library for the
exact command syntax). The default configuration file is normally
<samp class="file">~/.inputrc</samp>.
</p>
<p>Octave provides two commands for initializing Readline and thereby changing
the command line behavior.
