HotbarBumpers

HotbarBumpers

HotbarBumpers is a lightweight client-side Fabric mod that adds two configurable keybindings for navigating your hotbar without using the mouse wheel.

Instead of scrolling, you can bind Next Hotbar Slot and Previous Hotbar Slot to any keyboard key or mouse button, making it ideal for gaming mice, accessibility devices, controllers, and custom input setups.

• Vanilla-style wraparound between slot 9 and slot 1
• Client-side only
• Lightweight implementation with no unnecessary mixins
