Abstract
A cursor control apparatus allows switching between at least two modes of cursor position control operation; one of which provides emulation of cursor control keys with a graphic input device. The emulation of cursor keys provides control of cursor location in a digital mode in which the cursor is rendered only at locations corresponding to character areas, fields or cells as opposed to an analog mode in which the cursor may be positioned at higher resolution, either by providing multiple increment inputs to a cursor position controller or by direct application of signals to cursor key inputs of a processor. Enhancements of the digital mode of operation including cursor movement speed control are also provided.
