|
||
|
|
|
||
|
|
<p><a name="index-TUI-key-bindings-2904"></a>
|
||
|
|
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
|
||
|
|
<span class="sc">gdb</span> standard mode.
|
||
|
|
|
||
|
|
|
||
|
|
<a name="index-C_002dx-C_002da-2905"></a>
|
||
|
|
<dl><dt><kbd>C-x C-a</kbd><dd><a name="index-C_002dx-a-2906"></a><dt><kbd>C-x a</kbd><dd><a name="index-C_002dx-A-2907"></a><dt><kbd>C-x A</kbd><dd>Enter or leave the TUI mode. When leaving the TUI mode,
|
||
|
|
the curses window management stops and <span class="sc">gdb</span> 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.
|
||
|
|
|
||
|
|
<p><a name="index-C_002dx-1-2908"></a><br><dt><kbd>C-x 1</kbd><dd>Use a TUI layout with only one window. The layout will
|
||
|
|
either be ‘<samp><span class="samp">source</span></samp>’ or ‘<samp><span class="samp">assembly</span></samp>’. When the TUI mode
|
||
|
|
is not active, it will switch to the TUI mode.
|
||
|
|
|
||
|
|
<p>Think of this key binding as the Emacs <kbd>C-x 1</kbd> binding.
|
||
|
|
|
||
|
|
<p><a name="index-C_002dx-2-2909"></a><br><dt><kbd>C-x 2</kbd><dd>Use a TUI layout with at least two windows. When the current
|
||
|
|
layout already has two windows, the next layout with two windows is used.
|
||
|
|
When a new layout is chosen, one window will always be common to the
|
||
|
|
previous layout and the new one.
|
||
|
|
|
||
|
|
<p>Think of it as the Emacs <kbd>C-x 2</kbd> binding.
|
||
|
|
|
||
|
|
<p><a name="index-C_002dx-o-2910"></a><br><dt><kbd>C-x o</kbd><dd>Change the active window. The TUI associates several key bindings
|
||
|
|
(like scrolling and arrow keys) with the active window. This command
|
||
|
|
gives the focus to the next TUI window.
|
||
|
|
|
||
|
|
<p>Think of it as the Emacs <kbd>C-x o</kbd> binding.
|
||
|
|
|
||
|
|
<p><a name="index-C_002dx-s-2911"></a><br><dt><kbd>C-x s</kbd><dd>Switch in and out of the TUI SingleKey mode that binds single
|
||
|
|
keys to <span class="sc">gdb</span> commands (see <a href="TUI-Single-Key-Mode.html#TUI-Single-Key-Mode">TUI Single Key Mode</a>).
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<p>The following key bindings only work in the TUI mode:
|
||
|
|
|
||
|
|
|
||
|
|
<a name="index-PgUp-2912"></a>
|
||
|
|
<dl><dt><PgUp><dd>Scroll the active window one page up.
|
||
|
|
|
||
|
|
<p><a name="index-PgDn-2913"></a><br><dt><PgDn><dd>Scroll the active window one page down.
|
||
|
|
|
||
|
|
<p><a name="index-Up-2914"></a><br><dt><Up><dd>Scroll the active window one line up.
|
||
|
|
|
||
|
|
<p><a name="index-Down-2915"></a><br><dt><Down><dd>Scroll the active window one line down.
|
||
|
|
|
||
|
|
<p><a name="index-Left-2916"></a><br><dt><Left><dd>Scroll the active window one column left.
|
||
|
|
|
||
|
|
<p><a name="index-Right-2917"></a><br><dt><Right><dd>Scroll the active window one column right.
|
||
|
|
|
||
|
|
<p><a name="index-C_002dL-2918"></a><br><dt><kbd>C-L</kbd><dd>Refresh the screen.
|
||
|
|
</dl>
|
||
|
|
|
||
|
|
<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.
