[R] rgl keyboard shortcut for translation on Mac?

[Bryan Hanson]

Thanks Duncan... I see how to do it.  It appears that all 3 of my mouse
buttons are actually set to the trackpad button on my MacBook Pro.  So if I
assign any button via pan3d I get the same behavior, and can't get back to
the default.  I'll play with it!
