Scroll wheel It is used, as the name suggests, for scrolling. It can often also be used as a third mouse button by pressing on it. The wheel is often – but not always – engineered with detents to turn in discrete steps, rather than continuously as an analog axis, to allow the operator to more easily intuit how far they are scrolling.
