DeckTweaks
by n0ahn
DeckTweaks lets players change render distance, simulation distance, master volume and flight from simple keyboard shortcuts, without opening a menu or pausing the game.
What it does
Render distance can be raised or lowered, and simulation distance adjusted, while the game keeps running. Chunks reload right away, so the change shows at once. Master volume moves in 5% steps, and flight can be toggled from the keyboard, all from inside a session.
A short, unobtrusive notice appears in the lower-right area of the display to confirm every adjustment. The notification is a subtle, styled HUD message, so players always know what changed without a chat message filling up. The mod suits players who use a Stream Deck and want to map these controls to hardware buttons.
DeckTweaks runs on Fabric only and needs Fabric API. It is published for 1.21.11 alone, and it is not open source; the mod is released under All rights reserved. Only the client needs it, so servers run without it.
Key features
Render distance shortcuts
Keyboard shortcuts raise or lower render distance, and chunks reload immediately after each step.
Simulation distance control
Simulation distance can be tweaked during play, changing how far the game simulates without a restart.
Master volume in 5% steps
Master volume moves in fixed 5% increments from the keyboard, with no trip to the options screen.
Toast notifications
Each change shows a minimal toast in the bottom-right corner, keeping chat clear of status messages.

How it compares
Low Simulation Distance is a client-side Fabric mod for 1.21.1 under the MIT License, and it is open source, so its source code can be read and reused. Server Controls is a server-side only Fabric mod for 1.20 – 1.20.1 under the MIT License, so players join without installing it. DeckTweaks covers only 1.21.11, and its All rights reserved license means it is not open source.
