I looked online for instructions on how to put it back on, and found some Youtube videos and some picture-by-picture instructions. But still, for the life of me, I can't figure out how to get it back on. Basically, while reaching over to get something, her fingernail must've just gotten right under the key and popped it off. I still have the two plastic pieces that snap together to make the "scissor" as some sites call it, and the key itself. And, the if I press the nub, the "e" shows up as I type. Anyhoo, I made a Genius Bar appointment. Even if I'm outta warranty, they shouldn't give me any trouble putting it back on real quick, correct? And, the drive is kind of a nuisance... so if anyone has some "secret suggestions" to getting the key back on, I'd gladly take them!
