The scroll bars (Horizontal and Vertical) change you to maneuver up, 

down, and transversally your window simply by dragging the icon

 positioned on the scroll bar.

The horizontal scroll bar is positioned simply over the standing

 bar.

The vertical scroll bar is positioned on the correct aspect of the

 screen.

To move back and forward across your document, click and

 drag the horizontal scroll bar back and forward.

You would not see a horizontal scroll bar if the breadth of your

 document fits on your screen.

 vertical scroll bar up and down.
