Abstract
A keyboard may be provided that has keys overlapped by a touch sensor. The keyboard may have key sensor circuitry for monitoring switching in the keys for key press input. The keyboard may also have touch sensor circuitry such as capacitive touch sensor circuitry that monitors capacitive electrodes in the touch sensor for touch sensor input such as multitouch gesture input. The touch sensor may be formed from a layer of fabric. The fabric may be woven fabric or other fabric in which conductive strands of material serve as the electrodes for the touch sensor.
