About this Mod

Hotbar Swapper

Hotbar Swapper is a simple utility mod that allows the player to hold a button and scroll through the rows/columns of the inventory and swap them out.

Mod Use

By default, the mod waits for you to hold the toggle sprint key button to activate. Whilst activated, scroll to select rows, or hold the sneak key to narrow it down to columns (Configurable!).

Given the inventory:

Hotbar Swapper officially supports fabric, forge, neoforge for Minecraft 1.21.5, 1.21.4, 1.21.3. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
