A couple of small but pretty useful tips for expose on the mac.

1. If you use f9 or f10 for expose frequently & you also happen to have a number of different applications appear, you can scroll through each individual application on your desktop by clicking 'tab'.

2. Another useful tip is to click on f9 or f10, either will work and then press command-tab to bring up the application switcher. This will then give you the opportunity to bring to the front the application's window that you're looking to get to.

The two tips come in particularly useful if you're a) primarily a keyboard user b) tend to have multiple applications open on one desktop 'space'.

These may be familiar to an old school mac user, but to relative newbies I hope this is of some help. Ciao for now.
