Abstract
A handheld stylus for a digitizer includes a tip that is angled downward to meet the digitizing surface at almost, but not quite, a right angle. The body of the stylus is of a generally triangular cross section. Mounted upon the stylus are pushbutton switches actuatable by a force along a line essentially at right angles to the digitizing surface when the stylus is in use. An anti-rolling winged member keeps the stylus from rolling when it is laid over on its top after use.
