Abstract
Abstract A stylus is provided for changing modes of operation in conjunction with an electronic tablet. The stylus has a depressible erase end similar to a mechanical pencil or ink pen. By depressing or "clicking" the erase end, the stylus signals the tablet which mode is to be selected. Once in a particular mode, the erase end may be clicked at a rate different from the mode selection rate to select various options within the mode. A line thickness visual display is provided which is also similar to the functioning of a mechanical pencil. By twisting the pencil and viewing the visual display, an operator can change the thickness of the line and obtain visual feedback of an approximation thereof.
