 // Unlike TrackballControls, it maintains the "up" direction object.up (+Y by default).
 // This is very similar to OrbitControls, another set of touch behavior
 //
-//    Orbit - right mouse / touch: two-finger rotate
+//    Orbit - right mouse, or left mouse + ctrl/metaKey / touch: two-finger rotate
 //    Zoom - middle mouse, or mousewheel / touch: two-finger spread or squish
 //    Pan - left mouse, or arrow keys / touch: one-finger move
