Help?

So... on my iBook G4, my semi-colon key (seen here ";" and ":" ) is broken. Uh... it is ultrasensitive, and types out a semi-colon if I'm even just resting my pinky lightly on it, or if I even just brush a finger against it while typing on other keys. Ideas?

Oh, and today was my first day of teaching. It ruled.
