no, not really. the right mouse click opens what they call the contextural menu. this menu changes depending on the context, that is if you click on an object of away from objects.
The contectural menu is editable through the workspace editor and you can add menu commands to it. I have made some of my own simple menu commands and I have added these to the context menu along with things like paste in place, add surface, clip surface, etc.
You can make the context menu into a very powerful menu...
Oh yes, make sure you get a scroll wheel so that you can zoom in and out with the mouse.
