I have a Mac Book. The letter "p" on the keyboard is acting up. It's only that letter that is typing the wrong character. When I click it, it will type a variety of things, here's what I've gotten instead of a "p":
(Nothing)
/
p/
p0
Enter (it will actually act as the enter button and send me to the next line or submit something without me finishing to type it)

It is frustrating! Can I fix this myself? The key button is not broken, but I did notice a small crack on the surface under the key button.
