| <h3 class="section">25.2 TUI Key Bindings</h3> |
| <a name="index-TUI-key-bindings"></a> |
| |
| <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. |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-C_002dx-C_002da"></a> |
| </dd> |
| <dt><kbd>C-x C-a</kbd></dt> |
| <dd><a name="index-C_002dx-a"></a> |
| </dd> |
| <dt><kbd>C-x a</kbd></dt> |
| <dd><a name="index-C_002dx-A"></a> |
| </dd> |
| <dt><kbd>C-x A</kbd></dt> |
| <dd><p>Enter or leave the TUI mode. When leaving the TUI 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. |
| </p> |
| <a name="index-C_002dx-1"></a> |
| </dd> |
| <dt><kbd>C-x 1</kbd></dt> |
| <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. |
| </p> |
| <p>Think of this key binding as the Emacs <kbd>C-x 1</kbd> binding. |
| </p> |
| <a name="index-C_002dx-2"></a> |
| </dd> |
| <dt><kbd>C-x 2</kbd></dt> |
| <dd><p>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> |
| <p>Think of it as the Emacs <kbd>C-x 2</kbd> binding. |
| </p> |
| <a name="index-C_002dx-o"></a> |
| </dd> |
| <dt><kbd>C-x o</kbd></dt> |
| <dd><p>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> |
| <p>Think of it as the Emacs <kbd>C-x o</kbd> binding. |
| </p> |
| <a name="index-C_002dx-s"></a> |
| </dd> |
| <dt><kbd>C-x s</kbd></dt> |
| <dd><p>Switch in and out of the TUI SingleKey mode that binds single |
| keys to <small>GDB</small> commands (see <a href="TUI-Single-Key-Mode.html#TUI-Single-Key-Mode">TUI Single Key Mode</a>). |
| </p></dd> |
| </dl> |
| |
| <p>The following key bindings only work in the TUI mode: |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-PgUp"></a> |
| </dd> |
| <dt><tt class="key">PgUp</tt></dt> |
| <dd><p>Scroll the active window one page up. |
| </p> |
| <a name="index-PgDn"></a> |
| </dd> |
| <dt><tt class="key">PgDn</tt></dt> |
| <dd><p>Scroll the active window one page down. |
| </p> |
| <a name="index-Up"></a> |
| </dd> |
| <dt><tt class="key">Up</tt></dt> |
| <dd><p>Scroll the active window one line up. |
| </p> |
| <a name="index-Down"></a> |
| </dd> |
| <dt><tt class="key">Down</tt></dt> |
| <dd><p>Scroll the active window one line down. |
| </p> |
| <a name="index-Left"></a> |
| </dd> |
| <dt><tt class="key">Left</tt></dt> |
| <dd><p>Scroll the active window one column left. |
| </p> |
| <a name="index-Right"></a> |
| </dd> |
| <dt><tt class="key">Right</tt></dt> |
| <dd><p>Scroll the active window one column right. |
| </p> |
| <a name="index-C_002dL"></a> |
| </dd> |
| <dt><kbd>C-L</kbd></dt> |
| <dd><p>Refresh the screen. |
| </p></dd> |
| </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. |
