Logical buttons. Read the man page, the section about "ButtonMapping".

ZAxismapping translates wheel events into mouse button events, not the
other way round.

You want to use
   EmulateWheel yes
   EmulateWheelButton 4
to emulate the wheel by pressing one of these small buttons and moving
the mouse.

Use
   ZAxisMapping ""
   ButtonMapping "1 2 3 4 5"
to use the two buttons instead of a wheel. You might need to usei
"1 2 3 5 4" if order is reversed.

Yes, by just reversing the mouse logic. It would work w/o ZAxisMapping
as well.

Only by EmulateWheel. There's no ButtonRepeat or so. Might be an idea to
implement that, but so far nobody asked.
