R help - Dec 2009 - rgl keyboard shortcut for translation on Mac?

Hello Everyone.

I?m on a Mac, using rgl.  Thanks to all the developers and maintainers on
it!

If I drag the mouse, I can rotate the view, if I hold down the option key or
the ctrl key and drag, I get scaling (though at times I seem to alter the
perspective?).  Adding the shift key doesn't seem to modify anything.

So, what I can't find is a key combination that translates the object.  From
reading various documents about openGL, it seems there might be a toggle
somewhere, but I need a hint!  Or do I need to install/invoke some
additional command?

Thanks, Bryan

By default there's no translation action attached to a button on any 
platform.  The example code for rgl.setMouseCallbacks puts together most 
of one (though it doesn't work so well if you also rescale, and the 
bounding box isn't calculated perfectly).  It sets it on mouse button 
3:  on my Mac, you get that by Option clicking the main button.  You 
could run pan3d(1) to set it on button 1 if you can't find button 3.
