Abstract
A portable electronic device includes a touch-sensitive display including a display and display touch-sensors to detect touches, and a keyboard including mechanical keys associated with characters, the mechanical keys including depressible keycaps to output the characters and keyboard touch sensors to detect touches on the mechanical keys. A processor is coupled to the keyboard and to the touch-sensitive display to detect a touch at a location associated with a signature entry field displayed on the touch-sensitive display, in response to detecting the touch, enter a keyboard signature process, detect a moving touch on the mechanical keys of the keyboard, along a path of contact of the touch on the mechanical keys, and, in response to detecting completion of the moving touch, enter a signature defined by the path of contact of the touch on the mechanical keys into the signature entry field.
