By default, the Space bar (KEY_SPACE) is used to toggle between the two values. The field is PROTECTED so that the user cannot type directly into the field. The value that is displayed in the field when the user leaves the field is the value that is selected.
You can change the Space bar key assignment by modifying the data field event table FLDETP. If the Boolean toggle field is to be used in a scrollable region, you must also modify the scrollable region event table SRETP. See Chapters 37 and 39, "How Event Processing Works" and "Installing Event Functions and Modifying Event Tables," for more information.
