Using the mouse wheel, the mouse on the scroll bar or the <prior>,
<next>, <home> or <end> keys.  I guess these are the most common ones
for people trying to find out why Emacs does not behave like other
editors or applications like Firefox.

It's merely about the fact that "scrolling" as sketched above may move
point and consequently alter or simply discard the "selected text".
