index areas:  The regions in a HyperIndex parent object linked to a daughter object, which may be rectangular, circular, or quadrilateral in shape.  HyperIndex will display the daughter object when the mouse selects a point within the index area.  Active index areas can be revealed on the display of the parent object when the option “Show Index Areas” under the View window menu HyperIndex is on. (See also: daughter object, link, parent object.)
