Suggestion

In Forge ver, I can simply change keysetting in keybind menu but In fabric ver, there in no JEI keysetting in keybind menu
and I couldn't find at mod setting either

I don't think it's glitch

Thanks for the report!

This is a duplicate of #3000

Key bindings for Fabric have been implemented in JEI
for 1.20.1: 15.18.0.80+
