Expose & Spaces trigger wont work.

Ok, so my friend just bought a brand spanking new macbook.

We sit a stare at it for ages, but one tiny hitch. The shortcut for spaces wont work.
I think by default its set as F7 or F6. And we've tried using differnt buttons for the short cut but it wont work and its 2 days old..

Any ideas ?

On mine fn f8 opens spaces

On the new MacBook all the F keys are assign to other features... You'll probably need to to remap the control and deactivate the existing shortcut, e.g. for Dashboard.

Oh and make sure you enable spaces as well, I think it's turned off out of the box.
