Using it was like a magic trick. Words would just get a character truncated and merge. I could watch my fingers type and I would know what I had to do and my fingers would just merrily go on and do whatever they wanted.
There was some youtube video about a guy who set up a bike that had the turning backwards - you turned right and the front wheel went left. The funny part was that with a lot of effort the guy managed to teach himself to not be able to ride a normal bike.
But… ouch. From https://itsfoss.com/remap-copilot-key-linux/ and other sources, sounds like the Copilot button is LMeta+LShift+F23. Why a combo when using an esoteric key not on anyone’s keyboard anyway? Ugh. That’ll make it harder to sort out, though still possible.
