#! perl
#:META:RESOURCE:%.hotkey:string:activation hotkey keysym
=head1 NAME
kuake - kuake-like hotkey terminal
=head1 EXAMPLES
urxvt -kuake-hotkey F10
URxvt.kuake.hotkey: F10
=head1 DESCRIPTION
A very primitive quake-console-like extension. It was inspired by a
description of how the programs C<kuake> and C<yakuake> work: Whenever the
user presses a global accelerator key (by default C<F10>), the terminal
will show or hide itself. Another press of the accelerator key will hide
or show it again.
Initially, the window will not be shown when using this extension.
This is useful if you need a single terminal that is not using any desktop
space most of the time but is quickly available at the press of a key.
The accelerator key is grabbed regardless of any modifiers, so this
extension will actually grab a physical key just for this function.
If you want a quake-like animation, tell your window manager to do so
(fvwm can do it).
