InvSwap

by PhillY

InvSwap lets a player swap the inventory's lower rows with the hotbar using a single key press, and the mod runs on the client alone.

What it does

Pressing Mouse Button 4 exchanges slots 27 to 35 in the main inventory with slots 0 to 8 on the hotbar. The key can be rebound in the key bind settings menu. Because only the client needs it, players can use it in singleplayer and on multiplayer servers without any server-side install. It is released under the MIT License and is open source, with a public source code repository and issue tracker. Its only published build is for Fabric, targeting 1.21.8.

Key features

  1. Inventory to hotbar swap

    A single press moves the stored items from the inventory rows onto the hotbar and back, saving repeated dragging.

  2. Rebindable swap key

    The default button is Mouse Button 4, and the key can be changed in the key bind settings menu.

  3. Singleplayer and multiplayer

    The swap works in singleplayer worlds and on multiplayer servers, since it only changes the player's own client.
