ABSTRACT:
An input is disclosed that includes a zoom apparatus for increasing or decreasing the size of an image rendered on a display screen. The zoom apparatus has an actuator that is movable in a first direction to induce the image to zoom in. The actuator is also movable in a second direction to induce the image to zoom out. The zoom apparatus may include a sensor for detecting movement of the actuator in the first direction and movement of the actuator in the second direction. The input device may be a keyboard, for example, that includes a plurality of keys for inputting alphanumeric data, with the sensor also detecting actuation of the keys.
