AutoKeyBinds

Automatically fixes duplicated and unassigned keybinds without breaking player preferences.

AutoKeyBinds is a client-side utility mod for Minecraft Forge 1.20.1 designed to automatically detect and resolve duplicated or unknown keybinds in vanilla and heavily modded environments. It safely assigns only valid keybinds while respecting vanilla controls, mouse buttons, movement keys, system shortcuts, and any keybind manually modified by the player.

Once the player changes a keybind, the mod will never override it again. If no safe keybinds remain, the mod intentionally leaves them unassigned.
