rinnia | Shift-return!

My return/enter key and right-hand shift key on my laptop randomly stopped working this morning. Both Jaime and I have toyed with settings and the keys themselves, but nothing's worked. I'm typing this on a USB keyboard, which solves the problem somewhat, so at least there's not something horribly wrong with my lappy. Those two keys are just fuxxored. Thankfully, Jaime bought me AppleCare, so if this doesn't fix itself within a couple days, I'll contact the company and demand justice!

So... anyone encounter anything like this before? Ideas?
