An improved interactive text processing system is described in which the operator is provided with a ghost cursor on the scale line whose width varies in accordance with the different font size characters being typed and being displayed on an all-points-addressable (APA) display. Many text processing systems provide a scale line on the display device which has fixed character measurements. Some systems employ a ghost cursor on the scale line that is a fixed size and whose position represents the contextual position of the real cursor. This is advantageous to the operator when, for example, control characters that do not print are displayed on the screen at the operator's request to assist in formatting the text.
