You can specify the name of a module where SCA will look for the
  occurrence of a symbol.  SCA restricts the result to those
  occurrences that are in the specified module.

  Click on this button or the Module Entry box to activate this
  selection.  Enter the name or names of the modules that you want SCA
  to use.  Use a comma to separate multiple module names.  You may use
  wildcard characters, as defined by your particular operating system,
  in the module names.
