In 1984, the Macintosh had a light gray rectangle with a “scroll box” thumb, “gray area” track, and arrows pointing in opposite directions towards the content that would be exposed when the respective arrow was pressed. Arrows would scroll a single unit upon one click or auto repeat upon continuous press. Page buttons were removed, and the elevator track could be clicked in instead to move to the next section. Upon pressing the thumb, dragging it would bring it to that particular point unless movement was made far out of the scrollbar before release, aborting the action. An empty scrollbar was displayed when a window was not in focus or if the entire document was visible within the window.
