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.
