InputBehaviormouseOtherAxisMode Property

Affects how mouse axes other than X/Y contribute to the value. This affects the mouse wheel axis. Mouse Axis - Value range goes beyond -1 to 1 depending on speed of movement. This value is the same value returned by Unity's Input.GetAxis when axis type is set to Mouse Movement. Mouse Other Axis Sensitivity is multiplied by the axis value. Digital Axis - Any movement returns -1 to 1 and is smoothed by digital axes values. Mouse movement behaves like a button or keyboard key press. Mouse sensitivity does not affect this mode. Instead, all Digital Axis filters are applied.
