I’ve spent quite a lot of time polishing up my keyboard layout and mounting hardware, and I feel like I’m getting close to the ideal version for me. Unfortunately, after flashing my firmware with the latest update this morning, I noticed that my “4” key was no longer working. (Obviously, I’m not typing on it right now.) I don’t think I’d ever done a key-by-key test prior to that point, so I doubt it was the firmware flash that caused the problem.
On my Mac, Karabiner’s “Event Viewer” doesn’t seem to see any events happening when I press that key, so it’s not just generating something oddly non-printable.
Any thoughts on how to debug this?
