As you examine the Memory Map, you may wish to select display options
  that allow you to see more clearly those parts of the display you are
  most interested in.

  The Display Menu allows you to control whether you see segment type
  names within the Memory Map display, whether the display automatically
  scrolls to show the most recent activity, and whether you can compress
  the display.

  The Zoom Menu allows you to control the degree of magnification with
  which you see segments in the Memory Map.  Choosing the Far menu item,
  for example, shows an overview of memory.  Choosing Extremely Close
  shows a more detailed view of memory.
