Expose keyboard shortcuts
Expose is an awesome feature of Mac OS X, I use it so often it is almost impossible to live without. If you don’t use Expose, you should start, and MacApper has a nice list of keyboard shortcuts with each accompanying action.
• F9 – Show windows for all apps
• F10 – Show windows for one app
• F11 – Show desktop
• Tab – Cycle through applications and their windows
• Shift-Tab – Go to the previous application
• Arrow Keys – Move between windows in Exposé
• Spacebar or Enter – Bring selected window to the front
• Esc – Leave Exposé, ignoring window selection

FYI, F9 and F10 are backwards
You forgot the one I use the most: F11 – Show Desktop
Thanks! I didn’t know I could use tab to cycle through like that — this actually makes Exposé useful for me, finally.
if you are on the browser thing when you press “menu” on the remote (or apple, esc) press ctrl, alt, apple and escape to exit immediately without exit animation
Check out this new book. It has over 1,000 OS X keyboard shortcuts for 10 core Mac apps.
