2. Scroll Bar Positioning

Scroll bars are positioned either vertically (for up and down movement) or horizontally (for left and right movement). You can click with the mouse on the arrows at each end of a scroll bar or the area between the arrows. A "scroll box" travels the length of the scroll bar to indicate the approximate location of the material shown on the display in relation to the entire document. You can also drag the thumb with the mouse to move to a particular location.
