264=item kuake<hotkey>
265
266A very primitive quake-console-like extension. It was inspired by a
267description of how the programs C<kuake> and C<yakuake> work: Whenever the
268user presses a global accelerator key (by default C<F10>), the terminal
269will show or hide itself. Another press of the accelerator key will hide
270or show it again.
271
272Initially, the window will not be shown when using this extension.
273
274This is useful if you need a single terminal thats not using any desktop
275space most of the time but is quickly available at the press of a key.
276
277The accelerator key is grabbed regardless of any modifers, so this
278extension will actually grab a physical key just for this function.
279
280If you want a quake-like animation, tell your window manager to do so
281(fvwm can do it).
