     Should be something like:

	Joystick:
	Axis:     { "A": {"Direction": "X|Y|Z", "Value": number, "JNo": j, "Ext1": "extstr", "Ext2": "extstr", "Ext3": "extstr"} }
				- number => 0..1000 (normalized)
    
	RotAxis:  { "R": {"Direction": "X|Y|Z", "Value": number, "JNo": j, "Ext1": "extstr", "Ext2": "extstr", "Ext3": "extstr"} }
				- number => 0..1000 (normalized)
    
	Slider:   { "S": {"Index": 1|2, "Value": number, "JNo": j, "Ext1": "extstr", "Ext2": "extstr", "Ext3": "extstr"} }
				- number => 0..1000 (normalized)
    
	POV:      { "P": {"Index": 1|2|3|4, "Direction": "c | u | r | d | l", "JNo": j, "Ext1": "extstr", "Ext2": "extstr", "Ext3": "extstr" } }   
				- Index n=> 1..MaxPOV (setup of vJoy, max = 4)
				- Direction either of the chars (center (released), up, right, donw, left)

	Button:   { "B": {"Index": n, "Mode": "p|r|t|s|d", "Delay": msec, "JNo": j, "Ext1": "extstr", "Ext2": "extstr", "Ext3": "extstr" } } 
				- Button Index n => 1..VJ_MAXBUTTON (setup of vJoy - SC supports 60)
				- Mode optional - either of the chars (see below)

	Keyboard:
		Key:      { "K": {"VKcodeEx": "keyName", "VKcode": n, "Mode": "p|r|t|s|d", "Modifier": "mod", "Delay": msec, "Ext1": "extstr", "Ext2": "extstr", "Ext3": "extstr" } }  
					- VKcodeEx "s" either a number n=> 1..255 or a WinUser VK_.. literal (see separate Reference file)
					- VKcode n=> 1..255 WinUser VK_.. (see separate Reference file)
						if both are found the VKcodeEx item gets priority and the VKcode element is ignored
						if none is found the command is ignored
					- Mode optional - either of the chars (see below)
					- Modifier optional - a set of codes (see below)

		- Mode:     [mode]      (p)ress, (r)elease, (t)ap, (s)hort tap, (d)ouble tap           (default=tap - short tap is a tap with almost no delay)
		- Modifier: [mod[&mod]] (n)one, (lc)trl, (rc)trl, (la)lt, (ra)lt, (ls)hift, (rs)hift   (default=none - concat modifiers with & char)
		- Delay:    [delay]      nnnn  milliseconds, optional for Tap and Double Tap           (default=150 VJCommand.DEFAULT_DELAY, max 20_000 msec)     
		- JNo:      [joyNumber] >0 Joystick number                                             (default=1)
		- Ext1.3:   [string]    Optional user extensions that must be handled by the caller

      e.g.
      { "K": {"VKcodeEx": "VK_B", "Mode": "t", "Modifier": "lc"}}
      { "B": {"Index": 21 }}
