So I've had my iMac for a few years now, and couldn't be happier with it. Today I decided to switch out my crappy Linksys wireless router with a AirPort Extreme. Again, couldn't be happier. While I was at the store, I also decided to pick up a Mac wireless keyboard to replace the wired one that came with my iMac. Here's where my question lies. I setup the keyboard without a problem, but some of the F keys weren't working properly. I figured out how to fix that in System Preferences. But my keys from F7 to F12 aren't working. They are the Reverse, Play/Pause, Forward, and Volume keys. They have the same layout as my wired keyboard, but they're not doing anything when I press them on the wireless keyboard. I've spent a long time looking around System Preferences and I can't find how to get them to work. Any suggestions?
