Microsoft Windows has an easily adjustable option which allows users to speed up and slow down the mouse. Slowing the mouse movement can help overcome tremor problems, making it easier to click on small items. But as the pointer is slower to move the mouse requires more physical movement to get from one side of the screen to the other. This can become tiring.
