Right-clicking within an Ejs model, such as Dirac Delta Scattering, allows a user to examine the model contained in the jar file.
A Google search for a simulation often returns hundreds of hits but it is usually impossible to determine how the program was created. Programs created with Ejs are different because they contain an XML description of the model inside the compiled jar file. Executing the jar and right-clicking on the simulation allows a user to copy the model into Ejs as show in the figure. This simple operation exposes the model's details for inspection and modification. This feature allows the following teaching scenario:
