F3 Command
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.
F3 Command
An incredibly simple mod that adds one command: /f3.
why?
- you don't have to remember all the random combinations, autocomplete does that for you
- you don't have to play twister with your fingers every time you want to see hitboxes
- mac users rejoice! you no longer have to deal with the pain of system keybinds conflicting with F3 and messing up all your windows
uhhh yeah that's about it
