We have at least two regular users doing this with external three-
button or two+scrollwheel on Mac Parallels 5582.
We have a variety of apple mighty mouse, logitech, etc, in use.
We set
mouseport=ps2intellimouse
in plan9.ini. Three buttons. Wheel is button 2 (middle button,
execute things in acme) where applicable. I think for the mighty
mouse the special button-assignment (usually to `expose') features
need to be disabled in Mac System Preferences.
The wheel also scrolls in Plan 9.
On the macbook, I haven't hit the combo to make the built in trackpad
do 3 buttons. When we don't want to use an external mouse, we use
drawterm instead of a parallels terminal.
