Need both middle drag and middle+right drag for FreeCAD

Similar to this post I need to middle drag (to pan the drawing area) and middle+right drag (to orbit the object) with both a MagicMouse and MBP TrackPad.

middle+right drag sounds special enough that I marked this as a feature request. I'd love to hear that this is already possible. Any suggestions would be welcome.

Thanks,

P.S. (I'm still evaluating BetterTouch Tool, and FreeCAD and Blender where the main reasons I decided to consider it. This would definitely make it worth the money for me.)
