Wireless Keyboard Issue

Hi All,

I feel kind of stupid for not being able to figure this out but I figured someone else has maybe had this issue and knows how to fix it. My BF was messing around on my computer yesterday and somehow the top set of keys on my Apple wireless keyboard got all messed up. None of them are doing what they are supposed to do. Volume, brightness, escape, eject, etc. Nothing works. When I press the F12 button I'm getting my dashboard instead the volume going up. I tried restoring everything to default but nothing seems to be working. Any suggestions?
