About this Mod

This bug has been fixed in Vanilla 1.21.9 and onwards.

We have therefore decided to backport the fix to every Minecraft version that supports Fabric (excluding the first two versions in 1.14 as those Fabric versions don't work anymore)

This is a fork of Keybind Fix.

Keybind Fix Plus is a simple Fabric mod that aims to accomplish one major task: allowing for functional keybind conflicts.

In Minecraft, if two or more keybindings are set to the same conflicting key, the functionality of all but one keybinding is completely lost. For example, if you set both Jump and Strafe Left to the space bar, only the last of those functions that was set will work; you might strafe but not jump.

Keybind Fix Plus allows for mapping of multiple keybindings to the same key. Using the above example, with Keybind Fix Plus installed the player will both jump and strafe left.

This does NOT prevent all keybind conflicts. Two or more keybinds may still have incompatible functionality. If one keybind opens a door and another closes one, mapping both will still cause the underlying effects to fight (trying to open and close the door at the same time).

Frequently Asked Questions

Does Keybind Fix Plus need to be installed on the Minecraft server?

No. Modrinth marks Keybind Fix Plus as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Keybind Fix Plus require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.8, 1.21.7, 1.21.6. Files for different loaders are not interchangeable.

Keybind Fix Plus is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
