CVar cameraDistanceMoveSpeed

Sets the speed that the camera zooms in and out.

Notice that the speed of the mousewheel zoom has its own, unconfigurable, limit. Setting the speed higher than the mousewheel zoom will only affect the speed when e.g. swinging free of a wall, or switching between hardcoded camera views.
