ABSTRACT:
A ghost cursor indicates the relative horizontal position on a display screen associated with a printed document rendition of the displayed text and control codes. In a normal, or hidden codes, mode of operation the ghost cursor, placed on an escapement scale line, is vertically aligned with a text cursor which is positioned adjacent the displayed text code which defines the present point of operation. In the all codes mode, all text and control codes (such as required backspaces, tabs, etc.) are displayed. In the all codes mode the ghost cursor indicates the relative horizontal position on the display screen of the code associated with the text cursor, with forward or reverse escapement indicated by the control codes taken into account.
