Syntax:  OVERVIEW SOURCE

  Displays an overview of the buffer.

  This command displays the top level of detail for the entire buffer.
  LSE determines the relative level of detail of a line by comparing
  the indentation of the line with the indentation of other lines.  The
  editor's treatment of line indentation is influenced by indentation
  adjustment definitions.
