OneKey · Inventory & Action Optimization

OneKey is a modern, ultra-lightweight, zero-runtime-dependency inventory and action optimization mod for Minecraft 26.3 (Java 25), featuring native support for both Fabric and NeoForge.

Key Features

• One-Key Inventory Sort (Default: R): Instantly sorts open containers or player inventory by Category → Name → Count.
• 0ms Optimistic UI Sorting: Zero client latency with instant local sorting raycast and bundle audio cues, smoothly reconciled with the server.
• Hotbar Absolute Protection: Bottom 9 hotbar slots (0..8) are strictly excluded from all sorting and quick stacking, keeping your tools and weapons completely intact!
• Slot Locking (Alt + Left Click): Easily lock precious item slots with an intuitive high-visibility red border highlight. Locked slots are completely immune to sorting, stacking, and stash transfers, persisted per world save.
• Quick Stack & Quick Stash (Default: V & B): Automatically scans nearby containers within 6 blocks and merges items into existing matching stacks without manually opening every chest!
• Mouse Gestures:
  • Shift + Double Click: Fast batch transfer of all matching unlocked items to the opposite container.
  • Mouse Wheel Scrolling: Scroll up to pull 1 item from opposite container; scroll down to push 1 item to opposite container.
• Native In-Game Settings GUI (Default: K): Beautiful native GUI built directly on Minecraft vanilla screens — zero external UI library bloat (No Cloth Config needed)!
• Mod Conflict Auto-Detection: Friendly in-game notification when existing inventory mods (IPN, Mouse Tweaks, Item Scroller) are loaded.
