Personal communicator having improved zoom and pan functions for editing information on touch sensitive display
 A mobile, hand-held personal communicator includes a casing for housing a cellular phone, modem, and data processing system. Graphics image files are stored and can be selectively displayed on a touchscreen display. A zoom function magnifies areas of a graphics image, such as a fax image, that has been received and stored in the PC. When the zoom function is selected, the user touches the screen, and a magnification frame or window appears. When the user removes his/her finger, the area within the frame is magnified. The user can also drag the frame around the screen, while still touching the screen, to select a specific area to be magnified when the user releases the screen. A pan function allows the user to shift the image within a viewing area. The user can pan the image by touching the display at an initial touch point, and moving his/her finger keeping it in contact with the screen, to shift the touch point to a new touch point. Upon releasing the new touch point, the image is redrawn in a new position corresponding to the change in position between the initial and new touch points.
