An online, interactive system for text editing is described in detail, with remarks on the theoretical and experimental justification for its form. Emphasis throughout the system is on providing maximum convenience and power for the user. Notable features are its ability to handle any piece of text, the content-searching facility, and the character-by-character editing operations. The editor can be programmed to a limited extent.
