The Index view provides an interface for associating index keywords or named groups with specific Help topics. Index keywords are visible to the reader; only the author sees named groups. The upper left pane contains the index keywords that the reader can see while the lower left pane shows which topics are indexed to the keyword selected in the upper left pane. Note that the topics that are indexed by virtue of XE fields using Word are identified with the symbol in this pane. The right pane displays a sorted list of topics that can be indexed. The topics can be sorted and filtered in the same manner as in the Topic window.
