摘要

Information stored in a working memory of a word processor comprising symbols representing alpha-numeric text characters and word processor functions are displayed by means of a line display unit with alpha-numeric text characters and function symbols each occupying only one display position on the line display unit. When the meaning of a function symbol identified by a cursor positionable to identify the next display position to be processed is not evident, its meaning is automatically displayed in leftmost positions of the display unit, with suppression or shift of the text already displayed in said leftmost positions taking place as necessary to display the meaning of a function symbol.
