Keys You can use in EWJ demo:

The best way to control Jim is to have a 4 button joypad.

Esc             Exit to StartMenu.
                On StartMenu, exit to DOS.
P               Toggle Pause. 
M               Toggle CD-music (Using volume, cd IS playing anyway)
S               Toggle SoundFX. (If Off, doesn't start the Soundfx)
Arrowkeys       Use for control. On the numeric keypad, keys 7,9,1,3 act as
                combined directions.
Both Ctrls      Button 1 
Both Shifts     Button 2
Return          Button 3
Space           Button 3
Both Alts       Button 3
Tab             Button 4


Expected (current) layout of Controls:

Up              When hanging, Jim will pull himself up.
Down            Sit down.
Button 1        Jump. When hanging, let go.
Button 2        Whip.
Button 3        Shoot.
