|
<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>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 ‘<samp>SingleKey</samp>’. This can be used in
|
<samp>.inputrc</samp> to add additional bindings to this keymap.
