Do you mean a interactorStyle - hasA - Pan Manipulator?

I tried that and when I add the manipulator it seems to take over all the events…..I don’t get the left or right button - when I created the pan manipulator I only 
assigned it center button (2)

Do you mean a zoom Manipulator?

I’ll experiment and post some code if I can’t get it working….
