Abstract
An apparatus is described which includes memory areas for storing an image and trigger fields for the image, and a display which indicates a cursor in one of two configurations. Circuitry is provided for moving the cursor and enabling it to implement a select operation for a particular subroutine. The apparatus employs a method which enables the trigger fields to be invisible, which method comprises: displaying the image without trigger fields; and altering the cursor on the display from one configuration to another upon the cursor being moved into an invisible trigger field to thereby indicate to the user the presence of the trigger field.
