Scroll bars are everyone in Mac OS X and applications. There are two things that can happen when you click in the scroll bar, above or below the marker. The first is the window can move up or down one page. The second is the window can jump to a position in the document relative to the spot you clicked in the scroll bar. Switch between these two options in System Preferences, Appearance. Look for the “Click in the scroll bar to” option.
