74<p>The TUI also provides a <em>SingleKey</em> mode, which binds several
75frequently used <small>GDB</small> commands to single keys.  Type <kbd>C-x s</kbd> to
76switch into this mode, where the following key bindings are used:

141<p>Other keys temporarily switch to the <small>GDB</small> command prompt.
142The key that was pressed is inserted in the editing buffer so that
143it is possible to type most <small>GDB</small> commands without interaction
144with the TUI SingleKey mode.  Once the command is entered the TUI
145SingleKey mode is restored.  The only way to permanently leave
146this mode is by typing <kbd>q</kbd> or <kbd>C-x s</kbd>.

148<a name="index-SingleKey-keymap-name"></a>
149<p>If <small>GDB</small> was built with Readline 8.0 or later, the TUI
150SingleKey keymap will be named &lsquo;<samp>SingleKey</samp>&rsquo;.  This can be used in
151<samp>.inputrc</samp> to add additional bindings to this keymap.
