HotbarBumpers
by daa0502-max
HotbarBumpers gives the Next Hotbar Slot and Previous Hotbar Slot actions their own keybindings, so a mouse button or controller key can switch slots without the scroll wheel.
What it does
Two keybindings are added to the Controls menu, one moving the selection forward and one moving it backward. Each can be assigned to a keyboard key or a mouse button under Options, Controls, Key Binds, where the HotbarBumpers category appears. Selection follows Minecraft's native hotbar behavior, and moving past slot 9 wraps back to slot 1, as it does with the scroll wheel.
The mod is written for players who need a button in place of scrolling: gamers with mice that have extra buttons, accessibility devices, controllers and custom input setups. It is a client-side mod, so only the player's game needs it, and it runs on Minecraft Java Edition 26.2 and 26.3 with Fabric Loader and Fabric API. Files exist only for those two game versions, and the source code is available on GitHub under the MIT License, so the code is open source.
Key features
Next and previous slot keys
Two configurable keybindings move the hotbar selection one slot forward or backward.
Native selection behavior
Changing slots uses the same selection logic Minecraft applies to the scroll wheel, so the held item updates as usual.
Wraparound at the ends
Moving forward from slot 9 selects slot 1, and moving back from slot 1 selects slot 9.
Mouse and controller binding
Each action can be bound to any keyboard key or mouse button, which suits devices without a scroll wheel.
Lightweight implementation
The mod avoids unnecessary mixins, so it changes little of the game's code.

Safe Offhand is client-side only, covers 1.21.8 – 26.3 and is open source under the MIT License, but it handles the offhand slot instead of the hotbar keys.
