Abstract
A thesaurus feature for finding synonyms of words is provided for use with electronic typewriters having electronic spelling dictionaries for storing words in a data base contained in an electronic memory. Each word in the electronic dictionary which appears in the thesaurus is identified by a special code immediately following the word, so that the dictionary can be scanned quickly to determine if a given input word is in the thesaurus. If the word is in the thesaurus, the search for synonyms can proceed quickly. The input operations required of the typist are patterned after previously known operations to eliminate extensive learning or relearning on the part of the typist. Cascaded scanning of the display and listing operations are utilized to conserve time.
