4-WAY Cursor Control Key
Use the DOWN or UP 4-Way Cursor Control keys to select a

feature to work.
Navigation is not affected by the Screen Snapshot feature. Also, if Screen
Snapshot is enabled but there is no GPS receiver connected, pressing the
MARK key will capture the screen image and display an error saying that a GPS
position fix is required to create a waypoint.
The GOTO Key has multiple functions, depending on the situation:

not active, pressing the GOTO key displays the list of waypoints, so that
you can select the waypoint towards which you want to navigate.
