About this project
What does Multi Key Bindings add?
Multi Key Bindings
Github • Modrinth • CurseForge
Allows players to create multiple keybindings for the same action/function, add modifiers to their binds, and switch between key binding profiles.
This mod adds extra functionality to the native key binds screen. Simply click the "+" button next to any key binding and a new binding for the selected action should appear. This mod also adds support for modifier keys (left/right) shift, control, and alt.
Key binding profiles let you keep separate sets of bindings and switch between them from the profile dropdown at the bottom of the key binds screen, or with the /mkb command. You can also hide key bindings you never use to declutter the screen.

Versions and Compatibility
Created for Minecraft versions 1.20.x, 1.21.x, and 26.x
As of MKB version 1.4.0, there is support for key binding profiles (see
/mkb helpfor commands) and for hiding unused key bindings.
As of MKB version 1.3.0, there is support for key bind modifiers (e.g. Shift+K).
As of MKB version 1.1.0, this is now compatible with Controlling, so you can search and sort all your key bindings in the same screen.
Note that there are niche limitations: e.g. if binding a key to "Pick Block", you will not be able to drag to duplicate a block the way you would be able to with a mouse bind.
