The NavigationUnit class defines the possible values for the getVerticalScrollPositionDelta() and getHorizontalScrollPositionDelta() methods of the IViewport class.

All of these constants have the same values as their flash.ui.Keyboard counterparts, except PAGE_LEFT and PAGE_RIGHT, for which no keyboard key equivalents exist.
