I've done a search, and either I missed it, or it's not here. But, while on an internet page, on a BlackBerry (8700) is there a shortcut for page up and page down?

If you hold down "ALT" and scroll the track wheel it should page down.

Brilliant, thanks for the info! Seems I've been doing that, but did not realize that it was scrolling down a page at a time...

And for many more shortcuts see my tips site.
