A generic term covering a number of techniques used to create and view multidimensional documents, which may be entered at many points and which may be browsed in any order by interactively choosing words or key phrases as search parameters for the next text image to be viewed (see hot link). Generally a wimp style interface is used and tools are provided to help structure the text, create indexes of the text of a document, and to cross-reference between documents. The technique is related to full-text database systems. Hypertext systems provide facilities for windowing viewed text, selecting next view by mouse/keyboard marking of text fragments, searching the text database or indexes, and displaying the new text. See also hypermedia.
