hey everybody, i wanted to know if the shift key on the right side for the aluminum powerbooks had a little "button" like thingy, that feels soft to the touch, and keeps the keys suspended. the reason is because my little brother ripped off the shift key on accident, and while i have the key itself and the little part that goes into the holes, it doesn't work anymore, and just falls into place. if it does have this little thing, where could i find a replacement? i just need one, and since im going to college next week, i need it kinda soon. thanks!
