  Choose the Class View menu item to display all the
  classes in the current library.  CMS lists the classes
  in alphabetical order.

  Double click on a specific class to expand it to display
  the list of generations contained in the class.

  If you have opened multiple libraries, CMS displays
  the name of each library in the library list.  You must
  separately expand each library into its classes.
