If you own a Mac it can be a pain in the neck, or the fingers, always pressing the ‘fn’ key to access the f1-12 keys on the keyboard. But now there is an application called FunctionFlip that allows you to program the keys and their functions to your requirements.
FunctionFlip individually controls your MacBook or MacBook Pro’s function keys, turning special keys back to regular F-keys, or vice-versa. It’s compatible with all MacBooks and MacBook Pros, recent Apple external keyboards, iBooks, and PowerBooks. This will make life just a tad easier.
