ABSTRACT:
A font display and text editing system is disclosed. The system includes a display medium for displaying text characters. A memory stores digital information describing the shape of each alphabetical character of a plurality of sets of alphabetical characters, each of the sets of alphabetial characters defining a respective font. An input device sequentially generates a first signal identifying one of the alphabetical characters as a base character and a second signal identifying a different one of the alphabetic characters as an overlay character. A circuit responsive to the signals displays the base and overlay characters as a single complex character on the display medium.
