You can do literally anything you want in this regard; scrollwheel increments
are just another button. :-)
As mentioned earlier, what the software is seeing is *not* a physical action by
the user, but rather one or more symbolic abstractions ("keysyms" in X windows)
that have often been through several layers of complicated mapping
operations[1] depending on what input devices or methods the user is (thought
to be) using.
So, the best approach in documentation is to speak of the final symbolic form
("Scroll up") rather than specific physica devices or actions as much as is
reasonably possible. Trackballs, trackpads, pen tablets, touch screens, etc all
generally have some way of performing a "scroll" action, usually without a
"wheel" involved.
