AppleHotbarOprimiser
by sh4dowgirl
AppleHotbarOprimiser lets a keybind switch hotbar slots instantly, the way the mouse wheel does, for players who want faster swaps.
What it does
Vanilla Minecraft changes the selected hotbar slot only once per tick, and when a keybind is pressed several times in one tick only the highest index is kept. This Fabric mod separates keybind slot switching from the game tick, so a player can change slots any number of times within a single tick, matching what the mouse wheel already allows. It runs on the client alone, and the server does not need it. Files are published for 1.21.4, 1.21.10 and 1.21.11, and the source code is publicly available, though the mod is not open source and is covered by All rights reserved.
Key features
Instant keybind switching
Pressing a hotbar keybind changes the selected slot immediately rather than waiting for the next tick.
Unlimited slot changes per tick
The mod removes the one-change-per-tick limit, so several slot changes can happen inside a single tick.
Faster attribute swaps
Quick slot changes make it possible to swap attribute items in a fraction of the time, which matters in some combat situations.

What the author says
In vanilla Minecraft, the hotbar slot can only change once per tick, with the slot having the highest index being selected. This mod decouples hotbar slot switching from game ticks, allowing for an unlimited number of slot changes within a single tick. This enables faster attribute swaps, stun slams, and other PvP…
