On my MacBook Pro M3 chip, using Sonoma, my loWercase W key has stopped Working (uppercase is fine!). This is true both of the built-in keyboard and my Logitech MX bluetooth keyboard. I've tried restarting. So the problem is not dirty keys (uppercase is fine) or Bluetooth. I do a lot of Writing and need my keys to work (Note: auto-correct can use its lowercase W.
Suggestions?
Ah! I had one idea and tried it. I quit BetterTouchTool, which I know works with keystrokes. It gave me back my w. So now I need to figure out why BTT is blocking w keystrokes. One possible clue: I have enabled Caps Lock as a hyperkey.
