Don't limit your thinking to the physical device -- instead of looking
at "right mouse click", "left mose click", et. al., think more in terms
of "click event 1", "click event 2", etc.
The logical event can then be locally mapped to physical events, which
is under the control of the user -- if the user wants to swap left and
right buttons, that should be fine. For our Mac friends, this is just
one possible set of events:
Event # Physical Mapping
------- ----------------
1 Single click
2 Double click
3 <SHIFT> + single click
4 <SHIFT> + double click
5 <CONTROL> + single click
... ...
The point is, and this isn't even java-specific, that neither the user
nor the developer should be limited by the choice (or lack thereof) of
the pointing device.
