Fn F9 and F10 keys work on my new iMac
Just got the new iMac. All Fn keys work but the F9 and F10 functions do not. In system preferences it doesn't appear that functions are set up for F9 and F10. OS X keyboard shortcuts online shows that these keys should do the following:
F9 - Tile or untile all open windows
F10 - Tile or untile all open windows in the currently active application
Can anyone tell me how to get these to work?
iMac, OS X Mountain Lion (10.8.2)
