Function Keys on macbook pro
I recently made the switch (after a year of pining) from an ibook G4 to a macbook pro. I love the computer, however, I find myself missing some of the function keys that were on the previous model (mainly the F9 and F10 that used to show all the windows for a certain program and all the windows currently open). Is there anyway to reprogram the current keys so that they reflect the old fuctions? (right now they control the brightness of the keyboard, which I don't particularly care to have as a 'hot key').
Macbook Pro, Mac OS X (10.5.2)
