The edit path screen will display all of the paths defined at a specified origin location on the map. A path automatically gives a move to order to a unit which is at the origin location, based upon the unit being land, sea or air.
There can be up to four paths listed. Paths which do not have the Lad/Sea/Air type specified will be deleted when the screen is closed. Only one path is allowed to be specified of a certain type, but combinations of types are allowed.
To specify a Land/Sea/Air type for a destination, click on the Land/Sea/air button so that it is a highlighted color (Green/Blue/Red respectively).
