Mouse Key Inventory Fix
Java mod listed for Minecraft 1.16–1.20. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Fixes the almost ten-year-old issue with mouse key binds not working in inventories (see the bug report linked below).

Note:
Binding drop to mouse button 4/5 causes weird things in the creative inventory, I would recommend not doing so if you're planning on using the creative inventory.
