KeyDisabled
KeyDisabled turns off chosen Minecraft keybinds through a configuration file, so a server or a player can block keys such as F1 or F3.
What it does
Disabled keys are listed in a keydisabled.json file in the config folder of the game directory. Each entry is the ID of a Minecraft key, and the file is read so that any key named there stops responding. Editing the file updates the game in real time, so no restart is needed after a save. Setting the consoleLogs option to true prints the affected keys to the client console, which helps when checking whether a key is being blocked.
The mod is client-side only, so only the client needs it and servers run without it. It requires CatoAPI and Fabric API on Fabric. Builds cover 1.20.1 – 1.21.11 on Fabric, Forge and NeoForge, with the latest files at version 1.1 for 1.21.11 on Fabric and NeoForge and for 1.20.6 on Forge.

Use cases
Blocking debug keys
Keys such as F3 can be disabled in the list, for players who should not reach debug screens.
Limiting player input
A list of keys can be shut off to restrict certain actions on a shared client.
Who it’s for: Players who want to stop particular keys from working and server owners who set controls for players on a client. Anyone changing the list needs to know the ID of each key, which the wiki explains.
How it compares
Dedicated Shield Keybind is a client and server mod for 1.20.1 – 1.21.1 under All rights reserved, so it adds its own key and must be installed on both sides. Origins Extra Keybinds is client-side only under the MIT License and covers 1.19 – 26.1.2, a wider range than this mod's 1.20.1 – 1.21.11 builds. Drop Keybinds is also client-side only, open source under the Apache License 2.0, and limited to 1.21 – 1.21.8, so it does not disable keys in the same way.
