Comment 7 for bug 885304

If this is considered a bug in unity (3d) then the likely possibility would be 'while holding Alt pressing F1 doesn't toggle keyboard focus on the launcher

Otherwise if the launcher already has keyboard focus, (Alt+F1, Alt released), then as soon as Alt is re- touched focus is removed , either going to Hud (tap) or last opened window/Desktop (press

Unless , 'when launcher already has keyboard focus tapping or pressing Alt should not remove focus'?
