This simple mod allows you to lock any inventory slot by pressing a key to avoid accidentally dropping your sword, moving specific items into containers, equipping the wrong piece of armor, etc. Simply hover your mouse over a slot you want to lock and press the hotkey. Also works with selected hotbar slots.

The hotkey is configurable in Options -> Controls -> Key Binds -> Inventory -> Toggle Slot Lock
