I call BS on this nonsense. I still have a useless copilot key on my keyboard. But we'll see. I'm not going back.
Power of the default says that button will needlessly over exploit a ton of users.
There are ways, which involve using a software trap to capture it and then emit right control for a set period of time, but that's a workaround rather than a real fix.
