  As you examine the Memory Map, you may find that you need to adjust the
  type display to focus more clearly on your area of interest.  The
  Views-and-Types Display allows you to specify changes to multiple or
  individual segments of the same type.

  The Views-and-Types Display is actually two windows separated by a
  window sash.  You can expand the left window to show all the known
  types in your application.  The right window contains the display
  options (color, show status, expand status, and save status).
