Hotspots

  By default, hotspots are highlighted only when you point to
  them.

  To highlight hotspots continuously, choose Hotspots from
  the Topic window's View menu.  To remove the continuous
  highlighting, choose Hotspots from the View menu again.

  A shaded check button to the left of the Hotspot menu item
  indicates that highlighting is enabled.  The absence of a
  shaded check button indicates that highlighting is disabled.
