Narrator activates every time I use hotkeys.

So apparently you can activate the Narrator by clicking b + ctrl and there's no way to change that. 
Now, I'm using B as the hotkey for slot 4 and every time I sprint and try to use that hotkey, I accidentally activate the Narrator.

As of now, there's no way to change that. 
This should be changed to be able to set a hotkey for the narrator too.
I'm sorry if this is in the wrong section, I just wasn't sure if I should post it as a bug or suggestion.
