there was a thing you could do with cheaper key boards pull of the shift key, and pin down the rubber so i just about made contact, not not and then when any one pressed shift it would stick and spaz out or a set of keys so you get that drrrrrrrrrrrrrrrrrrrrrrrrrr sound, been a while since i saw it so its quite foggie in the headIt's better if you do it with the shift key.. Sticky keys
