In addition to modifying cursor movements as noted above, the 'fn' key in Mac OS X can also be used to switch the default functionalities of F1 to F12 (e.g., F1 and F2 for screen brightness control) to the standard function keys. As an example, in MS Word, the keyboard shortcut for toggling case is "shift + f3", a trick I recently learned. In the default setting, one must press "fn + shift + f3" to achieve the desired effect.
Any tricks to share? I'd like to hear them!
