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.
