User-unfriendly hardsoftware

If anything, touchpad scrolling functions seems so arbitrary, as in, every hard-software combination seems to do their own style.

With the contemporary touchpad model I have, scrolling is done by two-finger dragging, anywhere on the pad.
I remember a time when the touchpad area was divided into two sections, like 90%-10%, and scrolling vertically would be accomplished by dragging a single finger in the 10% region, mimicing dragging a sliderbar on the edge of the screen. (Maybe that's still the case for trivial touchpads that don't support multi-finger gestures?)
So, it's interesting to see that you use a third method of holding one finger and dragging the second. Not sure if it's a case of xkcd.com/927 (Standards) or xkcd.com/1172 (Workflow).

sigh. Everyone should just use the PgDn key, but at the same time, laptop keyboards have turned garbage in the past 25 years, first shrinking movement keys and then moving it to a Fn shift sequence. Outrageous. (Framework, you're in this as well!)
