1. Name the  Map "frame" that holds the layers and axes (e.g. called Map in the user interface)
2. Name the "overlays", which are the actual map layers (e.g. called Contours or Base in the user interface)

Use the .Name property of the Shape object to rename a layer or map object. For an example of renaming a map or the component layers, see below.
