More Keybinds

Cowboy’s Multi Keybinds

Have you ever wanted to perform one action using two different keys? Minecraft only allows you to assign a control to a single key. This feature solves that problem. You can give any keybind a second key or mouse button, and both will activate it. Want to attack using left-click and B? Sprint using both your usual key and a side mouse button? Go ahead.

How to use it

Press ] to open the Multi-Keybinds menu (you can change this key in Options → Controls). Click the button next to any control. Press the key or mouse button you want to use as its second trigger. Done.

The little X clears a second key if you change your mind. Your binds are saved and remain between sessions. It starts off empty; nothing is pre-set, so it won’t interfere with your controls until you decide to use it. It also won’t alter any keybinds you haven’t set up yourself.

Notes

This works with both held actions (like movement, sneak, and attack) and tap actions (like inventory, drop, and swap). It only runs on the client side. It is safe to use on any server—vanilla, realms, or otherwise—because it only manages your own input. This feature requires Fabric API.
