Weapon Testing Keys?

So, in “scripts” there’s weapontestingkeys.lua - here’s an excerpt:

keys = 
	-- command name -- key event -- data -- key bound name -- num keys -- bound keys
	{5906, eWeaponsFire,          	INKE_KeyDown,   0,  "Fire Weapons", {NUMPAD1} },

Is there a way to hook that functionality back up that we can do on our end as modders? The buttons don’t seem to work currently, unless I’m simply doing it wrong, lol (hit numpad 1, ship weapons will fire, right?).
