283=item kuake<hotkey>
284
285A very primitive quake-console-like extension. It was inspired by a
286description of how the programs C<kuake> and C<yakuake> work: Whenever the
287user presses a global accelerator key (by default C<F10>), the terminal
288will show or hide itself. Another press of the accelerator key will hide
289or show it again.
290
291Initially, the window will not be shown when using this extension.
292
293This is useful if you need a single terminal thats not using any desktop
294space most of the time but is quickly available at the press of a key.
295
296The accelerator key is grabbed regardless of any modifiers, so this
297extension will actually grab a physical key just for this function.

327We use it to implement a "distributed selection mechanism", which just
328means that one command uploads the file to a remote server, and another
329reads it.
330
331The commands can be set using the C<URxvt.remote-selection.store> and
332C<URxvt.remote-selection.fetch> resources. The first should read the
333selection to store from STDIN (always in UTF-8), the second should provide
334the selection data on STDOUT (also in UTF-8).
