I've read a bunch of posts here and elsewhere about how to get the Apple keyboard to do page-up or page-down, and suggestions tend to focus on using either the Fn or Command key + arrow-up/down.
This doesn't work for me in Microsoft Word for Mac. In both cases, it moves the cursor up by paragraphs only, not up or down the page. I have an older Macbook - first generation - running OS X 10.4.11, and am using an EXTERNAL keyboard - the wired, short one without the number pad.
Any suggestions? Is there a way to change the behaviour of certain keys in certain programs?
