The NEXTSTEP operating system further developed the idea, incorporating a feature whereby the right or middle mouse button brought the main menu ( which was vertical and automatically changed depending on context ) to the location of the mouse, thereby eliminating the need to move the mouse pointer all the way across the large ( for the time ) NextStep screen.
