Abstract

A digitizer eraser system and method are provided so as to include a writing/erasing digitizer pen, a tablet, and a tablet driver for use in conjunction with a computer and corresponding display screen. The user selects and deletes text or cells with one stylus stroke. In one motion, the user presses select, moves the erasing stylus across the material to be selected, then at the end of the selection lifts the stylus off the tablet to delete or erase the selected material. The system permits erasing of text or objects from the display screen via a keystroke function only when predetermined cursor shapes are being used on the screen. The keystroke function is chosen from a group of possible erasing keystrokes, with the selected keystroke being based upon the cursor shape being used so that undesirable erasing keystrokes are not used in certain situations. Additionally, the cursor shapes displayed on the screen are changed in accordance with whether the stylus is in a writing or an erasing mode or position. In certain PC-based embodiments where the operating system is window-based, subclassing is used so that selection and erasure by the stylus is only permitted in subclassed windows, not all windows being subclassed.
