    Properties, within the Information Window,
      contains display settings for the Identification symbols.
    
      - ID Symbol Color:
          sets color of ID symbols that appear on the surface upon
          location identification (left click on surface or volume in the
          Viewing
                Area). 
      - ID Contralateral Symbol Color:
          sets the color of contralateral ID location symbols displayed
        when Contra ID is active. 
      
      - Symbol Diameter: sets the size of
          the ID symbols that appear on the surface, except the most
          recently identified location. 
      -  Most Recent ID Symbol Diameter: sets
          the size of the most recently identified location. The default
          is a setting to a size slightly larger than the Symbol
          Diameter to distinguish the current location from previously
          identified locations.
