...how do you think people scrolled documents in Word before mice had scroll-wheels?

With the page up and page down keys, mostly, though you could drag the scrollbar.
Not sure about Word, but I believe many apps had a keyboard + mouse combination that enabled scrolling with any mouse movement without interacting with the scollbar, as well.
There is NO way that most people used page up down rather than drag the scrollbar in the late 90s.
