Abstract: A guide structure designed to locate blank spaces on a displayed form of a word processor through the utilization of a line scale and a character scale movably attached to and selectively positionable over the face of a conventional paper or like material form wherein indicia formed on each of the scales serves to establish coordinates of any blank space on a material form regardless of its location. The coordinates are then related to the operator of the word processor along with informational instructions for filling the blank space.
