Keyboard function keys messed up

Hello,
No idea what happened here. all the normal keys on my mac keyboard worked fine on friday when at work and i come in today and they are all messed up. how do i get them back to there defaults?

Example, f12 now goes to the desktop instead of actually increasing the volume and f11 is the dashboard instead of decreasing the volume, etc. I am not sure if an update or something got installed or what.

I have tried going into keyboard under system preferences and restoring defaults but that didn't work. I also tried powering the keyboard off and on and still a no go. any other ideas?

I am using the bluetooth keyboard and running snow leapord.

Thanks for the help.
