City RPG 1.2.3 - Problems

Bonjour,
I’m here because I want your help.
I’m just trying to edit my init.lua to change the bindkey of the “+menu” but I don’t know how…
I guess it’s over here but… :


	if not input.LookupBinding("+menu_context") then
		CMenuKey = "NOT BOUND"
	else
		CMenuKey = string.upper(input.LookupBinding("+menu_context"))
	end
	
	if not input.LookupBinding("+menu") then
		QMenuKey = "NOT BOUND"
	else
		QMenuKey = string.upper(input.LookupBinding("+menu"))
	end
	
	if not input.LookupBinding("gm_showhelp") then
		ShowHelpKey = "NOT BOUND"
	else
		ShowHelpKey = string.upper(input.LookupBinding("gm_showhelp"))
	end

Because I want to have:
F1 = Player Menu
F2 = Helps
F3 = Inventory
Q = Spawn Menu

Sorry for my bad english.
Merci.
