Two kinds of online help about the debugger and debugging are available
  during a debugging session:
      Context-sensitive help, which is information about an area or
      object in a window or dialog box

   -  Task-oriented help, which consists of an introductory help topic
      named 'Using the Heap Analyzer' and several subtopics on specific
      debugging tasks

  Related context-sensitive and task-oriented topics are connected
  through the list of Additional Topics in the Help windows.
