I noticed that pressing spacebar when a listbox has the focus scrolls
the listbox to the first selected item.

I'm intercepting the spacebar press event at form level for stopping and
starting audio playback, so I would like to remove the default behaviour
form the listbox, and also from other buttons and controls.

I tryed ( following a tutorial ) to subclass the listbox class, but I
was able to intercept only mouseclicks, not the keydown event (I
imagined that is the keydown event I must intercept and don't pass for
further processing)

any idea?
