In less, but also in copy-mode. No modifier keys seem to have any effect. It
could be my
terminal environment, I guess? KDE/Konsole.

Well, 3 seems natural for me. With mouse-enabled vim, the mouse wheel also
scrolls 3 lines.
I don't think it's Konsole doing that, I assume it must be a default in vim.

It would be nice to have this be configurable, and it also makes sense to me
that both scroll
rates be the same.

Makes sense.

Good question! I guess the catch-all answer is to provide configuration
allowing the user to
set fast and slow scroll speeds in addition to the standard one. Maybe a single
configuration
option could take one, two, or three parameters:
mouse-scroll-speed <normal> [<fast> [<slow>]]
I would guess a sensible default would be that fast is double the value of
normal, and slow
is 1?
