Hmm, I'm not sure you understand, or I do for that matter.
From what I read, you want to say a trigger, but also require a key press before the command is activated?
Vocal Trigger is say, Missiles Fire
Begin Device State Check : Keyboard Key 'Ctrl' Is Pressed
Press 1 key and hold for 0.06 seconds and release
End Condition
What I said was, you can say the command, but nothing will happen till you Hold down CTRL before you say the trigger.
Using just the Recognition Global Hotkey is just the same as having VA Listen On, and wouldn't seem to give you what you asked for. A Vocal command, with also a key press before the command is triggered.
You can say, Missiles Fire, but if you weren't Holding CTRL down, nothing will happen.
If I read you right, that is what you asked for. If I misunderstood, explain....
