<dl compact="compact">
<dt><code>complete (<span class="key">TAB</span>)</code>
<a name="index-complete-_0028TAB_0029"></a>
</dt>
<dd><p>Attempt to perform completion on the text before point.
The actual completion performed is application-specific.
The default is filename completion.
</p>
</dd>
<dt><code>possible-completions (M-?)</code>
<a name="index-possible_002dcompletions-_0028M_002d_003f_0029"></a>
</dt>
<dd><p>List the possible completions of the text before point.
When displaying completions, Readline sets the number of columns used
for display to the value of <code>completion-display-width</code>, the value of
the environment variable <code>COLUMNS</code>, or the screen width, in that order.
</p>
</dd>
<dt><code>insert-completions (M-*)</code>
<a name="index-insert_002dcompletions-_0028M_002d_002a_0029"></a>
</dt>
<dd><p>Insert all completions of the text before point that would have
been generated by <code>possible-completions</code>.
</p>
</dd>
<dt><code>menu-complete ()</code>
<a name="index-menu_002dcomplete-_0028_0029"></a>
</dt>
<dd><p>Similar to <code>complete</code>, but replaces the word to be completed
with a single match from the list of possible completions.
Repeated execution of <code>menu-complete</code> steps through the list
of possible completions, inserting each match in turn.
At the end of the list of completions, the bell is rung
(subject to the setting of <code>bell-style</code>)
and the original text is restored.
An argument of <var>n</var> moves <var>n</var> positions forward in the list
of matches; a negative argument may be used to move backward
through the list.
This command is intended to be bound to <tt class="key">TAB</tt>, but is unbound
by default.
</p>
</dd>
<dt><code>menu-complete-backward ()</code>
<a name="index-menu_002dcomplete_002dbackward-_0028_0029"></a>
</dt>
<dd><p>Identical to <code>menu-complete</code>, but moves backward through the list
of possible completions, as if <code>menu-complete</code> had been given a
negative argument.
</p>
</dd>
<dt><code>delete-char-or-list ()</code>
<a name="index-delete_002dchar_002dor_002dlist-_0028_0029"></a>
</dt>
<dd><p>Deletes the character under the cursor if not at the beginning or
end of the line (like <code>delete-char</code>).
If at the end of the line, behaves identically to
<code>possible-completions</code>.
This command is unbound by default.
</p>
