I have a non-Apple keyboard connected to my MacBook Pro. Is there a way to make the F7 F8 and F9 do the previous song / play-pause / next song actions like they do on the built-in keyboard?
CoverSutra, among other things, will let you set your shortcuts the way you want it
It's main feature (at least for me) is its Music Search. Its like Spotlight for iTunes. Activate it with a keyboard shortcut and search away!
