During the Opt-in I noticed that the Control key no longer gave me the Show Path Distance info any more and reported it. I was disappointed to see that it was still an issue. That made me wonder about it. I have since discovered that the input screen/game will no longer recognize my Control, Shift and Alt keys any more. All those keys work in other games/programs as there is no physical issue with my keyboard. It's not a really old one but its not a new one either. It's a Logitech G-19 keyboard running the 8.27 gaming software. I had to change the above keybinding to the Backspace key in order to get it working again. So something has changed in your code that affects certain keyboards running this software. I don't believe there was any automatic update happening with it as I always turn that stuff off so I can update when and if I'm ready. Hope that helps to remedy this.
