Secondary Key

⌨️ Secondary Key

Secondary Key is a lightweight client-side Fabric mod that lets you assign a second key to any Minecraft keybind while keeping the original key working.

For example:

• Hotbar Slot 3 → 3 + Mouse 4
• Open Chat → T + ` “
• Toggle Perspective → F5 + V

Both keys will trigger the same Minecraft action.

✨ Features

• Assign one secondary key to any Minecraft keybind
• Original keybinds continue to work normally
• Supports keyboard keys
• Supports mouse buttons
• Secondary key settings are saved automatically
• Fully client-side
• Lightweight and simple
• Useful for PvP and custom control setups
