SwapColumn

A Minecraft Fabric mod that lets you swap items between your hotbar and the inventory slots directly above it — without opening your inventory.

How It Works

SwapColumn adds a vertical swap column above any hotbar slot. When triggered, a small menu appears showing the items stacked above your selected slot. Choose one and it swaps instantly into your hotbar.

Opening the Menu

Mode 1 — Number Key: Press the number key of the hotbar slot you are already on. Example: you are on slot 3, press 3 — the SwapColumn opens above slot 3.

Mode 2 — Keybind: Press your configured SwapColumn key (unbound by default). Set it under Options → Controls → SwapColumn.

Selecting an Item

Click mode:

• Mode 1: press 1–4 to select a row (1 = current hotbar item, cancels the swap)
• Mode 2: press 1–3 to select a row, press the SwapColumn key again to cancel

Scroll mode: Hold the opening key and scroll to highlight a row, then release to confirm.

Configuration

The config file is located at .minecraft/config/swapcolumn.json and is created automatically on first launch.

{
  "enableCycling": false,
  "enableSlotTexture": true
}

Option	Default	Description
enableCycling	false	When scrolling, wrap around from top to bottom and vice versa. Note: scrolling down on the first action always wraps regardless of this setting.
enableSlotTexture	true	Render slot backgrounds using the vanilla hotbar texture. Disable if your texture pack causes visual issues.

Mod Menu Support

With Mod Menu installed, both options can be toggled in-game from the mod list — changes apply immediately. Mod Menu is optional: without it, edit the config file directly (file edits take effect on the next game start).
