// For this single key example, we only need one keylist, KEY1. This specifies
// that the Numpad 0 keyboard key (Key=96) should act as a toggle. And toggle
// between the two Presets of PRES1, PRES2.  Which will change the Const1 being 
// passed to the shader code from 1.0 to 0.0 as floating point numbers.
// Type=1 is toggle, Type=2 is momentary.
