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.

Hey clamlol,
I have a keyboard from 2021, so i dont think that key jamming would be the problem. I dont that there is another app that uses fn + f3 + B, but if it does, i couldnt find it. I have windows 11 and my keyboard model is Razer BlackWidow V3 Mini HyperSpeed i think. I hope that you can do something with this information, thanks.

(in my last response there were some spelling mistakes, this is the right one)
If it’s not a hardware problem then this may be due to a system keyboard shortcut, possibly a hardcoded one, as was the case with MC-278386. Try playing Minecraft Classic. You should be able to build with both B and Fn + B. If the latter does not work, then unless your browser is intercepting the key combo, your OS must be, and would do the same for regular Minecraft. Let me know how it goes. (Not sure if it’s possible to test the full Fn + F3 + B in Minecraft Classic, on Firefox the F3 input brings up the search field, but perhaps it would work on another browser.)
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).
