Haha, of course. Don't take it the wrong way, just having some fun. Had a laugh when I saw the post, because it seemed pretty straightforward. But maybe that's only because I actually DO know that F10 is the right key.
Its F10 by default. It's not on mine, and I'm not sure why more don't do this: I have mine set from F10-F13, it makes more sense to me, but when I had my iBook, it was from F8-F11, because F12 is eject.
But maybe I'm just weird.
.. i think there is less F buttons on the books.
