The Services Menu

The service StereoPlot is made available to other applications.  If text is selected, it can be used as data for StereoScope by selecting the StereoPlot option from the Services menu.  This will be highlighted if text is selected.  If the data is not appropriate data for the StereoScope application, errors will occur and a plot will not be produced. 

This feature is activated if your application is located in one of the standard paths.

It might require you logging out and back in to activate the service.  (Helpful hint, I found that the undocumented command 
make_services
will update the services without logging out and back in.)
