Secondary Key

by imthefixpot

Secondary Key lets a second key or mouse button trigger the same Minecraft action as the original binding, for players who want quick hotbar switching or alternative controls.

FabricClient-side onlyMIT License26.2 – 26.3

What it does

Each binding gets a secondary input. Once set, pressing either the primary key or the secondary one fires the same game action, so the original key is not replaced. A typical setup assigns Mouse 4 as the secondary key for hotbar slot 3, and pressing either the number 3 key or Mouse 4 selects that slot. The mod supports both keyboard keys and mouse buttons, and settings are saved automatically between sessions.

Secondary Key is client-side only, so only the player's client needs it and servers run without it. It targets 26.2 and 26.3, with 1.1.0 for 26.3 as the latest file. Installation needs the Fabric loader and Fabric API, and it is released under the MIT License, though it is not open source. Java is required to run the game.

Key features

  1. Two keys per action

    Each Minecraft action can have a second key or mouse button that works alongside the original binding.

  2. Keyboard and mouse input

    Secondary bindings accept both keyboard keys and mouse buttons, so a side button can serve as a hotbar trigger.

  3. Saved settings

    Secondary key assignments are stored automatically and restored the next time the game starts.

  4. Lightweight design

    The mod adds only the secondary binding layer and does not change other game systems.

Use cases

Hotbar switching in PvP

Players can bind a mouse button to a hotbar slot so that fast switching does not require moving the hand from the mouse.

Alternative control layouts

A player can keep a familiar key for an action and add a second key that suits a different hand position.

Who it’s for: Players who want an extra key or mouse button for the same action in Minecraft 26.2 or 26.3, with Fabric installed.

What the author says

Both keys will trigger the same Minecraft action. If your normal key for Hotbar Slot 3 is 3, you can assign Mouse 4 as the secondary key.
