This is the Using Help overview. The Help system
  works in much the same way as other DECwindows
  applications, so learning how Help behaves will teach
  you a lot about how to use other applications.

  You need to be able to perform four basic tasks:

  - Select an additional topic
  - Return to a previous topic
  - Use context-sensitive help
  - Exit from Help

  For more information on any of these tasks, double
  click MB1 on the appropriate additional topic below. If
  you want help on all of the tasks, start with Selecting
  Additional Topics.

  To dismiss Using Help click on the Exit button below.
