16 The DJGPP keyboard handler provides an 'emergency exit' sequence which
17 you can use to kill off your program. If you are running under DOS this
18 is the three finger salute, ctrl+alt+del. Most multitasking OS's will
19 trap this combination before it reaches the Allegro handler, in which
20 case you can use the alternative ctrl+alt+end. If you want to disable
21 this behaviour in release versions of your program, set this flag to
22 FALSE.
