Holding your left mouse key down, click in the layout and drag out a box to represent your Paging area, or the area that will change while the rest of the display remains static.
If the Paging
area does not draw exactly where you want it, you can move it by releasing the left mouse key to get a yellow box around your Paging
area. Then just grab the small white box in the top left corner and drag the Paging
area to the desired location.
