well i was sat next to my router sorting things out with it and then he phone rings, i reach to pick it up and it falls off the desk and lands on my powerbook keyboard. we now my alt key has fallen off. i have the top and 2 bits of plastic. i can work out how they all go together but i cant get them all to go back together as it is some form of scissor movement and i cant get a bit to jook over another without lifting it up so i can see what im doing but then it wont reach. help what can i do? is there an easy way of getting it back on?
