<h3 class="section">32.5 Readline vi Mode</h3>

<p>While the Readline library does not have a full set of <code>vi</code>
editing functions, it does contain enough to allow simple editing
of the line.  The Readline <code>vi</code> mode behaves as specified in
the <small>POSIX</small> standard.
</p>
<p>In order to switch interactively between <code>emacs</code> and <code>vi</code>
editing modes, use the command <kbd>M-C-j</kbd> (bound to emacs-editing-mode
when in <code>vi</code> mode and to vi-editing-mode in <code>emacs</code> mode).
The Readline default is <code>emacs</code> mode.
</p>
<p>When you enter a line in <code>vi</code> mode, you are already placed in
&lsquo;insertion&rsquo; mode, as if you had typed an &lsquo;<samp>i</samp>&rsquo;.  Pressing <tt class="key">ESC</tt>
switches you into &lsquo;command&rsquo; mode, where you can edit the text of the
line with the standard <code>vi</code> movement keys, move to previous
history lines with &lsquo;<samp>k</samp>&rsquo; and subsequent lines with &lsquo;<samp>j</samp>&rsquo;, and
so forth.
</p>
