Ahaha i was just coming to say that i figured it out.

I added this to the top "def PageDefaultHud_KeyPressed( args ):" in PageDefaultHud.py

    from Pagelayout import Pagelayout
    from Pagelayout import ToggleDisplayRudderHeading
    if args.Key == MenuKeyManagerWrapper.Keys.C:
        if Menu.MenuKeyManager.IsKeyPressed( MenuKeyManagerWrapper.Keys.Shift ) == False:
            if Menu.MenuKeyManager.IsKeyPressed( MenuKeyManagerWrapper.Keys.Ctrl ) == False:
                ToggleDisplayRudderHeading()

could probably make that key configurable in the setup script.
