Keybindslots

"Universal mod — supports Fabric, Forge, NeoForge, and Quilt across multiple Minecraft versions."

Keep multiple named snapshots of your Minecraft controls and client options, and switch between them whenever you need. Keybind Slots makes it easy to save, organize, and restore your settings without manually copying options.txt.
Create slots for different play styles, modpacks, or preferences. Save your current settings to a slot, rename it, load it later, or delete it when you no longer need it. Confirmation prompts help prevent accidental saves and deletions.
Choose between two storage types:
Global Saves are shared across Minecraft versions and profiles.
Version Saves stay separate for the Minecraft version or launcher profile you’re currently using.
Open the in-game interface with K by default. You can change the key in Minecraft’s Controls settings. The screen only opens during gameplay when no other screen is open—not from the title screen or while you’re using another interface.
Please note: Loading a slot replaces your active options.txt. This includes all options stored in that file, not only keybinds. Back up your settings first if you want to keep a separate copy.
Available for multiple Minecraft versions and mod loaders; make sure to download the file that matches your game version and loader.
