Mouse Tweaks 2.31 for Minecraft 26.2: Controls, Setup and Desync Checks

Mouse Tweaks changes how the mouse handles stacks inside Minecraft Java inventory screens. It adds faster right-button distribution, left-button collection and transfer gestures, and wheel-based movement between a container and the player's inventory. It does not create items or bypass the server: the server still decides whether an inventory transaction is accepted.

The current creator-listed files checked August 28, 2026 are Mouse Tweaks 2.31 for Minecraft 26.2. MineBrush has not moved an item with these builds. Valuable items, multiplayer acceptance, custom GUI behavior, and input-mod interactions remain untested.

Loader label note: this guide uses Forge as the primary walkthrough route in the compatibility card. Forge is not the only supported loader: the exact creator records below also provide NeoForge and Fabric files. Use one row only, and apply Fabric API solely to the Fabric branch.

Pick the exact 2.31 build

All three records are client-side releases. Use one JAR for the loader in the active profile. Fabric API's declared relation applies to the Fabric file; it is not an instruction to add Fabric API to Forge or NeoForge.

Know what each gesture does

The creator documentation describes several separate behaviors. Right-button dragging can place items when you cross the same slot more than once. Left-button dragging while holding a stack can collect matching items, and Shift plus left-drag can transfer matching stacks. Shift plus left-drag with an empty cursor can transfer across slots. Wheel movement pushes or pulls items between inventories.

Learn one action at a time in a chest containing disposable cobblestone. Do not begin with shulkers, named tools, enchanted gear, bundles, or modded storage. Fast input is useful only when you can predict where each stack goes.

Install and prove the baseline

1. Confirm Minecraft 26.2 and the active loader.
2. Close the game and copy the working profile.
3. Remove wrong-loader or duplicate Mouse Tweaks files.
4. Add the exact 2.31 JAR and its declared Fabric relation when applicable.
5. Open a single chest in a copied world and test right-drag, left-drag, Shift-drag, and wheel movement separately.
6. Close and reopen the chest to confirm the resulting inventory is server-authoritative.

A stack appearing under the cursor is not final proof. On multiplayer, watch for snap-back, ghost stacks, delayed corrections, unexpected shift-transfer order, or a container reopening with different contents.

Test custom containers safely

The source repository says Mouse Tweaks targets screens based on Minecraft's standard container-screen class and provides an API for other GUIs. A modded inventory can replace input handling, special slots, filters, or transfer rules. Compatibility with a vanilla chest therefore does not prove compatibility with backpacks, machines, terminals, or custom crafting screens.

Use one disposable stack in one slot type. Test normal click first, then exactly one Mouse Tweaks gesture. Close and reopen the screen after every action. If the custom screen fails while a vanilla chest works, record the container mod, both versions, loader, gesture, slot, and the smallest repeatable sequence.

Fix unexpected wheel direction or transfer order

The project documents settings for wheel search order and scroll direction, including an inventory-position-aware mode. Record the original values before editing. Change only one option, restart if the configuration path requires it, and repeat the same chest layout.

If another inventory-sorting, scrolling, controller, or accessibility mod also binds the mouse wheel, disable one handler in a copied profile. Rebinding both at once can hide which mod consumed the input.

Fix a crash or missing controls

• Match the JAR to Minecraft 26.2 and the loader exactly.
• On Fabric, verify the declared Fabric API relation before adding optional Mod Menu.
• Remove duplicate versions and test Mouse Tweaks alone.
• Preserve the complete crash report and active mod list.
• For a GUI-specific problem, include the container mod and exact screen.

Mouse Tweaks is designed around mouse input. A controller mapper, trackpad gesture layer, accessibility utility, or touch translation can generate different events. Test that input layer explicitly and keep its version in the report; the creator's client-side label does not certify every pointer device.
