navigation keys to make or confirm a selection.

The navigation keys roll over. Pressing one of the navigation keys will lead
the user down a navigation path. Each time the key is pressed, another step
in the path is taken. Once the end of a navigation path is reached, pressing
the key one more time will bring the user back to the beginning of the path.
Pressing the opposite key will move the user through the navigation path in
the opposite direction. Once the beginning is reached, pressing the opposite
key will take the user to the end of the path.
