Hi, I'm one of those keyboard maniacs, Keyboard Maestro, QuicKeys, etc. So the first thing I did was look at the keyboard specs on the new powerbooks. Our 15-inch Powerbook G4s have 77 keys (U.S.) or 78 keys (ISO) The new 12- and 17- inch Powerbook G4s have 78 keys (U.S.) or 79 keys (ISO). What's the additional key? Jerry
