Some guest O/S's expect to be controlled using various multiple-key combinations, or chords.  For example, the <CTRL>-<ALT>-<DEL> chord is often needed to start, stop, or login to some guests.  Using these keys directly is not possible, because some keystrokes are intercepted by the server O/S or the windowing system.  Oracle VM Manager provides a technique that allows these keystroke combinations to be forwarded to the guest O/S which can then perform the expected function.

The technique used is to make some keys sticky, that is, by pressing the key multiple times at once (an action rarely used on keys such as <CTRL>) the sticky mode is set so that the next key press is sent to the guest O/S with the <CTRL> attribute added.
