MSS (More Slot Swap)
Managing your inventory mid-fight can mean the difference between victory and a swift respawn. MSS (More Slot Swap) is a client-side Fabric, Forge, and NeoForge mod that lets you move, swap, and refill items without ever opening your inventory screen. Whether you are bridging in the Nether or juggling totems in a raid, this add-on keeps your hands on the keyboard and your eyes on the action.
What Makes MSS (More Slot Swap) Stand Out
The core advantage is simple: you can rearrange gear during play. No more fumbling through menus while a Creeper sneaks up behind you. The mod offers seven distinct swap methods, and you can bind them to five different keys. You can even assign the same swap type to multiple keys for different rows or slots.
For example, you could set key 1 to swap your main hand with inventory row 3, key 2 to row 2, and key 3 to row 1. This flexibility means your muscle memory adapts to the mod, not the other way around.
Supported Versions and Loaders
MSS (More Slot Swap) for Minecraft supports a wide range of versions. Fabric users can run it on 1.21, 1.21.1, and 1.21.4. Forge players have options across 1.16.5, 1.18.2, 1.19.2, 1.19.4, and 1.20.1. NeoForge covers 1.20.1, 1.20.6, 1.21, and 1.21.1. The mod requires Cloth Config API to function.
Because it is entirely client-side, you do not need to install anything on the server. This makes it perfect for survival multiplayer, public servers, and realms where you lack admin permissions.

How to Install MSS (More Slot Swap)
Installing the mod is straightforward. First, ensure you have the correct loader for your Minecraft version. Download MSS (More Slot Swap) from a trusted source, then place the .jar file into your mods folder alongside Cloth Config API. Launch the game and verify the mod appears in your mod list.
If you prefer a hassle-free setup, the foxygame.net launcher offers a curated add-on catalog where MSS (More Slot Swap) can be installed with a single click, complete with automatic version matching and updates. This removes the guesswork of manually tracking down compatible builds.
Configuring Your Keys
By default, the mod's keybinds conflict with vanilla Minecraft controls. Open your key bindings menu and either disable or reassign the conflicting keys. Then press F12 in-game to open the MSS GUI. Select keys 1 through 5 at the bottom of the screen, choose a swap type on the left, and enter the slot or search string. Press Save for each key, and you are ready to go.
Advanced Settings
Slot Lock only affects the Vertical swap type. Search Priority applies to Slot-Search and Search-Search modes. You can divide priority into three areas and skip specific slots entirely. The HUD and HUD background can be toggled with the X and Z keys during play.
Compatibility Notes
MSS (More Slot Swap) works well with Automatic Tool Swap and Inventory HUD+, though you should hide the mod's HUD when using similar overlays. If you run InventoryProfilesNext, disable Auto Refill and enable picking items into empty locked slots to avoid conflicts. Always test with other inventory-manipulating mods before relying on them in a hardcore world.
