Mouse Tweaks

Mouse Tweaks replaces the standard RMB dragging mechanic, adds two new LMB dragging mechanics and an ability to quickly move items with the scroll wheel.

Installation

1. Install a compatible mod loader:
- 1.16.5 and later: install Minecraft Forge or Fabric.
- 1.14.4 and later: install Minecraft Forge.
- 1.12.2 and earlier: install either Minecraft Forge or LiteLoader (or both).
2. Put the Mouse Tweaks jar-file into the mods folder in your .minecraft directory.

Mouse Tweaks is purely client-side. There is no server-side component.

Extras

Mouse Tweaks API

Configuration file: .minecraft/config/MouseTweaks.cfg

Tweaks

RMB Tweak

Very similar to the standard RMB dragging mechanic, with one difference: if you drag over a slot multiple times, an item will be put there multiple times. Replaces the standard mechanic if enabled.

Configuration setting: RMBTweak=1

Hold your right mouse button:

Drag your mouse around the crafting grid:

You can drag your mouse on top of existing items:

LMB Tweak (with item)

Lets you quickly pick up or move items of the same type.

Configuration setting: LMBTweakWithItem=1

Hold your left mouse button to pick up an item:

Drag your mouse across the inventory. Items of the same type will be picked up:

Hold shift and drag. Items of the same type will get "shift-clicked":

LMB Tweak (without item)

Quickly move items into another inventory.

Configuration setting: LMBTweakWithoutItem=1

Hold shift, then hold your left mouse button:

(Mouse cursor is not visible for some reason)

Drag your mouse across the inventory. Items will get "shift-clicked":

(Mouse cursor is not visible for some reason)

Wheel Tweak

Scroll to quickly move items between inventories. When you scroll down on an item stack, its items will be moved one by one. When you scroll up, items will be moved into it from another inventory.

Configuration setting: WheelTweak=1

Configuration setting: WheelSearchOrder=1

When you scroll up, the mod will search for items from last to first (when this is set to 1) or from first to last (when this is set to 0).

Configuration setting: WheelScrollDirection=0

Set this to 1 to invert the default scroll actions. So, when set to 1, scrolling down will pull the items and scrolling up will push the items.

Set this to 2 to enable the inventory position aware scrolling. Scrolling up will push the items into the other inventory if it's above the selected slot, or pull items from the other inventory if it's below the selected slot. Vice versa for scrolling down.

Obsolete / Removed Settings

These settings existed in older Mouse Tweaks versions but were removed since.

Configuration setting: OnTickMethodOrder=Forge, LiteLoader

Mouse Tweaks can use multiple APIs for an OnTick method that it requires. You can use this setting to control the API it prefers. This shouldn't really matter at all. If a method isn't supported (for example, you don't have the API installed) the mod will proceed to check the next ones.

Configuration setting: ScrollHandling=0

Toggles between "smooth scrolling, minor issues" (0) and "non-smooth scrolling, no issues" (1). When set to smooth scrolling, minor issues may be experienced such as scrolling "through" JEI or other mods. When set to non-smooth scrolling, those issues will not happen, but the scrolling will be a little non-smooth. Non-smooth scrolling works only with the Forge OnTick method.

This option is set to smooth scrolling by default because the aforementioned issues require rather specific conditions to trigger and aren't very impactful, while scrolling items is something you do all the time and want the experience to be as good as possible.

Compatibility

Mouse Tweaks is compatible with everything based on GuiContainer (as long as the behavior isn't changed too much).

If your GUI isn't based on GuiContainer, or if you want to improve compatibility (making Mouse Tweaks ignore some slot, for example), take a look at the API documentation.

Modpacks

Feel free to include Mouse Tweaks in modpacks.

ABOUT THIS LISTING

This page describes Mouse Tweaks by YaLTeR. The description and screenshots are the author's own, imported from their listing on Modrinth on 31 August 2026: https://modrinth.com/mod/mouse-tweaks

Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.modrinth.com, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

MOD LOADER

This release is built for Forge. A mod built for one loader will not load under another — Fabric mods do not run on Forge, and vice versa.

GAME VERSION

Built for Minecraft 26.2. Minecraft mods are tied to an exact version: a 1.21.4 build will refuse to load on 1.21.5.

DEPENDENCIES

Check the author's listing for required libraries before you start the game — a missing dependency shows up as a crash on launch, not as a warning.

1. Install Forge for the Minecraft version you play, if you have not already.

2. Download the .jar with the button on this page. Do not unzip it — a mod jar is installed as it is.

3. Put it in your mods folder:

Windows — %APPDATA%\.minecraft\mods

macOS — ~/Library/Application Support/minecraft/mods

Linux — ~/.minecraft/mods

4. Launch the game with the Forge profile selected.

ON A SERVER

Anything that changes world generation or gameplay has to be installed on the server as well as on every client. Client-side visual and interface mods do not.

UPDATING

Replace the old .jar rather than adding the new one beside it. Two versions of the same mod in the folder is a crash on launch.
