<a name="index-TUI-single-key-mode"></a>

<p>The TUI also provides a <em>SingleKey</em> mode, which binds several
frequently used <small>GDB</small> commands to single keys.  Type <kbd>C-x s</kbd> to
switch into this mode, where the following key bindings are used:
</p>
<dl compact="compact">
<dd><a name="index-c-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>c</kbd></dt>
<dd><p>continue
</p>
<a name="index-d-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>d</kbd></dt>
<dd><p>down
</p>
<a name="index-f-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>f</kbd></dt>
<dd><p>finish
</p>
<a name="index-n-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>n</kbd></dt>
<dd><p>next
</p>
<a name="index-o-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>o</kbd></dt>
<dd><p>nexti.  The shortcut letter &lsquo;<samp>o</samp>&rsquo; stands for &ldquo;step Over&rdquo;.
</p>
<a name="index-q-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>q</kbd></dt>
<dd><p>exit the SingleKey mode.
</p>
<a name="index-r-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>r</kbd></dt>
<dd><p>run
</p>
<a name="index-s-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>s</kbd></dt>
<dd><p>step
</p>
<a name="index-i-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>i</kbd></dt>
<dd><p>stepi.  The shortcut letter &lsquo;<samp>i</samp>&rsquo; stands for &ldquo;step Into&rdquo;.
</p>
<a name="index-u-_0028SingleKey-TUI-key_0029"></a>
</dd>
<dt><kbd>u</kbd></dt>
<dd><p>up

<dd><p>where
</p></dd>
</dl>

<p>Other keys temporarily switch to the <small>GDB</small> command prompt.
The key that was pressed is inserted in the editing buffer so that
it is possible to type most <small>GDB</small> commands without interaction
with the TUI SingleKey mode.  Once the command is entered the TUI
SingleKey mode is restored.  The only way to permanently leave
this mode is by typing <kbd>q</kbd> or <kbd>C-x s</kbd>.
</p>
<a name="index-SingleKey-keymap-name"></a>
<p>If <small>GDB</small> was built with Readline 8.0 or later, the TUI
SingleKey keymap will be named &lsquo;<samp>SingleKey</samp>&rsquo;.  This can be used in
<samp>.inputrc</samp> to add additional bindings to this keymap.
