Controls which input gesture adjusts the Studio camera's fly speed while
navigating.
Controls which mouse-and-keyboard gesture is used to adjust the Studio
camera's fly speed while navigating in the 3D viewport. The selected binding
intercepts the mouse scroll wheel (or touchpad pan gesture) when the
designated modifier is active, changing camera speed instead of zooming. This
setting is exposed in Studio's Camera preferences as
Camera Speed Adjust Binding and defaults to
CameraSpeedAdjustBinding.RmbScroll.
