探囊取物（Su's Instant Swap)

The mod's instant swap key is bound to the vanilla inventory key by default, so one press moves the item under the cursor or the hand item into the hotbar or inventory without opening a separate menu. A separate Left Alt key handles swaps inside the open GUI, and its binding can be changed on its own. Holding the B key over a Sophisticated Backpacks backpack opens it, and swapping inside the backpack interface works from there.

Since version 3.0.0 the mod supports several backpack mods, including Sophisticated Backpacks, Traveler's Backpack, Packed Up, L2 Backpack and Beans Backpacks. The mod is open source under the GNU Lesser General Public License v3.0 or later and is client-side only, so servers run without it. Builds exist for 1.20 – 26.2 across Fabric, Forge and NeoForge, and the latest files are 3.0.0 for 26.2, published on 2026-09-12. In-game settings open from Mod Menu on Fabric, and a player who prefers can instead change the values in the config file inside the config folder.
