Isn't there an "fn" key combination to do page up/down? On a MacBook Pro, it's fn-up arrow and fn-down arrow (and fn-left/right arrow is home/end). Is it the same on a MacBook?
Using the "fn" key worked fine. Sorry about the silly question, this is my first mac and i'm still getting used to how it works. Thanks for your help. I'm off to give Oceania a try.
