If you use expose on all windows, and then hit the Tab key....it will toggle between expose of each app you have open. If you don't understand what I mean, open 2 documents in word and 2 safari windows. Hit F9 for expose, then hit Tab. Has anyone known this, or am I just REALLY slow (I'm assuming I missed this a while back). Anyways, it is a very handy button...what do you guys/girls think?
