Unable to toggle hitboxes
John Parker
Published May 07, 2026
Here's the basics:
I'm on a Windows 10, playing on Minecraft Java Edition, 1.16.1
When I press any other Debug command (That consists of Fn + F3) EXCEPT for Fn + F3 + B, it works.
Pressing Fn + F3 + B does... nothing.
The B key works perfectly fine when I'm typing, I looked around everywhere on how to enable hitboxes, and everyone just said, "Press F3 + B". There IS one person unable to turn on hitboxes here, but I didn't find any helpful pointers.
Does anyone have the same problem, and what are the possible reasons for this problem? I can give more information if needed.
Thanks!

Are you holding all 3 keys at the same time? Or maybe you/your settings reprogrammed the shortcuts. Try Fn + F3 + Q to check all the debug shortcuts.
