[R] rgl keyboard shortcut for translation on Mac?

Hello Everyone.

I¹m 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
