Hi Michael...thanks for your reply. I went to preferences>expose>keyboard shortcuts, but the function key options didn't include "hiding all windows". The options were "All Windows", "Application Windows", and "Show Desktop". It's odd because the "Fn" key as well as Fn+F11 do the same thing, they just thumbnail the windows that are open. How do I get the computer to move all the windows aside so that I can access something that's on the desktop, like a Word doc, etc.?
