<p>The TUI installs several key bindings in the readline keymaps
|
||
|
|
(see <a href="Command-Line-Editing.html#Command-Line-Editing">Command Line Editing</a>).
|
||
|
|
The following key bindings are installed for both TUI mode and the
|
||
|
|
<small>GDB</small> standard mode.

the curses window management stops and <small>GDB</small> operates using

its standard mode, writing on the terminal directly. When reentering
|

the TUI mode, control is given back to the curses windows.

The screen is then refreshed.

<dd><p>Use a TUI layout with only one window. The layout will
|
||
|
|
either be ‘<samp>source</samp>’ or ‘<samp>assembly</samp>’. When the TUI mode
|

is not active, it will switch to the TUI mode.

When a new layout is chosen, one window will always be common to the

previous layout and the new one.

<p>Because the arrow keys scroll the active window in the TUI mode, they
|
||
|
|
are not available for their normal use by readline unless the command
|
||
|
|
window has the focus. When another window is active, you must use
|
||
|
|
other readline key bindings such as <kbd>C-p</kbd>, <kbd>C-n</kbd>, <kbd>C-b</kbd>
|
||
|
|
and <kbd>C-f</kbd> to control the command window.
