I have the wireless keyboard (without the numeric keypad) for my iMac. It is not the original keyboard that came with my computer because I spilled a drink on the other one, unfortunately. Anyways, the F1-F12 function keys worked perfectly fine with my old keyboard, but when I synced up this one the keys either do nothing or something they aren't supposed to. I have done all of this: - System Preferences > Keyboard & Mouse > Keyboard > Use all F1, F2, etc. keys as standard function keys: I have this checked. - System Preferences > Universal Access: This is enabled. I've also tried restoring the defaults. Please help? Thank you!
