Hi Owinfrey,
There's a section on key commands for the NGX in the "NGX Introduction" manual (page 69).  You might want to check that out.  This option allows you to assign key commands to an extensive number of NGX functions through the NGX's own CDU.  Some have already been assigned and you may want to start with those to try them out.  One of our forum members posted this link some time ago, which you may find helpful as it lists the default PMDG NGX key commands :

I'm not familiar with Leo Bodnar's cards, but my understanding is that you can connect hardware buttons and switches to them which will then be recognised by Windows as "joystick" buttons.  FSUIPC can then assign key commands (such as the NGX ones) to such "joystick" buttons which means that when you press one, this will have the same effect as typing the command into your keyboard.  Hope this helps.
 
Oh and BTW, you may want to sign your posts with your name from now on !
