Junction Screens control application navigation but are never shown to the user.
These screens have navigate scripts associated with them which control the navigation to and from the junction screen.
This example script selects menu option 3 on a menu, emulates the pressing of the enter key and checks that the correct screen is displayed:
Typically there are one or more scripts navigating away from a junction screen towards other junctions and one or more scripts navigating towards it from other junctions.
Collectively these scripts define a navigation network between junctions.
