Simple Hotbar Switcher
by Ragek34
Simple Hotbar Switcher lets players swap hotbar slots with inventory slots using keyboard shortcuts, and it is a Fabric mod for 1.21.11.
What it does
Pressing Alt with a number from 1 to 9 exchanges the selected hotbar slot with the inventory slot directly above it, so an item can be moved into the hotbar without opening a container screen. Pressing Alt with 0 swaps the whole hotbar with the closest hotbar row in the inventory in one action. The mod also offers a button that switches the inventory hotbar with one press.
Swaps are sent to the server with optimized packet handling, which the author describes as keeping them responsive at moderate ping. The mod works on either side, and neither needs it: a client alone runs it fully. A server-side mode exists for cases where the server needs to stay consistent with clients; without that mode only the client sees the changed items, which can appear as ghost items to other players. The mod requires Fabric API at the version matching 1.21.11. The code is open source under the MIT License.
