● The select function will call the currently selected menu entry. This can trigger an action
such as docking, a service such as EStop, or display a message such as the Help
message. This function is mapped to user button 1 by default.
● The back function allows the user to return back to the menu from a message screen. If
the menu is already showing the menu entries, it will return to showing the first 5 menu
entries and the first entry will be highlighted.
