A module can be either a Python or Lua script or a Java class file. Information about modules appears in the window below the module tree. For example, go to the Modules tab and click on the ReverseEngineeringGeneric module. Double click a module and you will see its methods.

Double clicking a method name will copy it into the GRT shell window. You will see how useful this can be in Section 10.3, “Using the GRT Shell”.
