Also worthy of note is that the modifier keys are 'uncoupled'. This means that you can toggle the exposé features by say using left shift key if you never use it, or the right command key, etc. Problem is that I've noticed that I tend to use all the keys at various parts of a session, so I haven't yet figured out how to do this without accidentallying exposing exposé at an unwanted moment.

Wow, that's new in 7B85 (or 7B74 - it wasn't in 7B68).

And by that, I mean the modifier keys doing Exposé.

Hint for anybody with a laptop noticing that the right-side modifiers aren't working - it looks like the laptops send the right-side modifiers as left-side modifiers, so the shifts are the same, etc.

Also interesting is that you can set Exposé to be, say, option-right click, or control-right click. Very cool.
