In my minecraft the debug modifiers aren’t working. I have tried updating my drivers, restarting minecraft and using shift + fn +f3 + Q, B, etc. or only using fn + f3 + Q,B, etc. But it still doesn’t work. I have also tried it in a single player world and in a multi player server, but in both of them the debug modifiers don’t work. The only ones that do work are the reload chunks and reload resource packs debug modifiers, which is even weirder that only those work. I hope that someone knows how I can fix this.
It’s possible that this is due to key jamming, a hardware issue common on older keyboards. Can you confirm that these input combinations work fine in other apps (if you can even find another app that can accept eg. Fn + F3 + B)? If they do, or if you can’t find an app to test with, please reply with your OS version and keyboard model (or computer model if you’re using a laptop keyboard).
