Probably. I'm not sure what X users with >3 button mice + wheel do
with their ZAxisMapping.  There are probably enough apps that are
hardwired to use mouse-4 and mouse-5 as the wheel, to force such users
to go to the trouble of mapping buttons 4 and 5 to 6 and 7 so they can
leave 4 and 5 free for the wheel.

I thought there was a way of handling z-axis events in X directly
without the mapping, but after searching now I think I might have
been misled by GDK or vi documentation (both of which basically do the
above function-key-mapping).
