OnKey Scripts
Complete .lua files meant to be dropped into scripts/OnKey/ — see Getting Started for how OnKey binding/KEYVAL works if you haven’t read that yet.
OpenCheatMenu.lua — Opens the game's own dev cheat menu with a single hotkey press.
The whole entry point of MrxCheatBootstrap is one call, _G.Cheat.DisplayOptions() — this just wires it to a hotkey instead of typing it into the console every time.
local KEYVAL = "f2" -- must be in the first 10 lines -- pick any key you like, see the note below
_G.Cheat.DisplayOptions()
Confirmed working — this reuses the exact _G.Cheat.DisplayOptions() call already live-tested on the MrxCheatBootstrap page; wiring it to OnKey doesn’t change its behavior, just when it fires.

Picking a different key: KEYVAL (or the matching entry in lua_loader.ini’s [OnKey] section) needs a recognized key name — see Your First Mod for the mechanics of how KEYVAL gets picked up. For the full list of valid Windows virtual-key names/codes to choose from, see Microsoft’s own reference: Virtual-Key Codes (this is the same link the loader’s own auto-generated lua_loader.ini points you to).
