Context info	MouseWheelEvent.wheelDelta, MouseEvent.altKey, MouseEvent.ctrlKey, MouseEvent.shiftKey, MouseEvent.metaKey, and UIEvent.view are in use. MouseEvent.screenX, MouseEvent.screenY, MouseEvent.clientX, MouseEvent.clientY, and MouseEvent.button are in use if the wheel is associated to a pointing device. MouseEvent.relatedTarget indicates the event target the pointing device is pointing at, if any. UIEvent.detail is not in use.
