List Widget - Zoom user to default extent when selection is cleared

[GJW]

Right now when you use the "Clear Selection" tool on the List Widget or otherwise clear your selection, there is not a way to set up an action to zoom the user back to the default extent of the map.  My users are frustrated because this is what they expect to happen.

The only workaround I found is to create a line layer of the default area boundary and use list widget zoom to the layer. You need to make the list look like a button. The only thing I don't like is that the boundary will be highlighted.
