When I set narrator control as ctrl + something, I don't need to use ctrl.

RebindAllTheKeys as I believe

How do you even set the narrator control key? I could not find a button for it in the controls menu.
I know it is ctrl + B by default.

I have another mod for it

Can you tell me the name of the mod? Or even better a link to it?

I wrote another mod that does a similar thing ("rebind narrator"). This is not an AMECS bug, Minecraft handles the narrator keybind in a very low-level way before going through the regular Minecraft keybinds system.

A lazy implementation of changing the narrator key (like the one in my mod) still doesn't go through to the minecraft keybindings system. It will check the key's GLFW key token but won't call any fancier keybinding methods. So it has no idea what AMECS has to say about the key binding.

Yea, I'm using rebind-narrator-1.18-1.0.0.

I published 2.0.0 the other day which should resolve this
