    How about north and south?  That extends to east and west easily for
    multi-wheel mice.

`wheel-up' and `wheel-down' are better because they are similar to the
names of the vertical arrow keys, which are `up' and `down'.  I don't
think people will confuse this with the `down-' prefix for mouse keys.
(There is no `up-' prefix.)
