2.5.6-10 One Structure for Vertical, One for Horizontal Movement

Only one scrolling/paging structure should be used for vertical movement in a display and one for horizontal movement in a display.

Additional Information:
The placement of the scrolling/paging structures should clearly indicate the function for vertical or horizontal movement. For example, one scroll bar might be placed along one of the side borders of the display for vertical scrolling and another scroll bar might be placed along the top or bottom (opposite the menu bar) of the display for horizontal scrolling.
