Key Filter
by shihyeon
Key Filter lets players lock, hide or disable individual key bindings in the Minecraft Controls screen, and it is a client-side mod for Fabric, NeoForge and Quilt.
What it does
Each key binding can be set to one of three independent states: locked, hidden or disabled. A locked binding cannot be overwritten by an accidental rebind. A hidden binding is removed from the vanilla Controls list, which keeps the list short for players who use only a few keys. A disabled binding is ignored by the game entirely, including keys that another mod would normally consume.
Pressing F8 in game opens the Key Filter configuration screen, where a list of bindings shows a button for each one and the buttons toggle its state between Lock and its reverse, Hide and its reverse, and Disable and its reverse. The mod is open source under the GNU Lesser General Public License v3.0 only, and its source code and issue tracker are public. Files are published for Fabric, NeoForge and Quilt, and Fabric API is required on Fabric and Quilt installs.
Only the client needs the mod, so players can use it on any server without asking the server owner to install anything. The Key Filter config screen is the only place where the states are changed, and the choices apply to the client's own controls.
Key features
Lock protection
A locked binding keeps its key when a rebind is attempted, so an accidental change does not overwrite it.
Hidden entries
Hidden bindings disappear from the vanilla Controls screen, keeping the list focused on the keys in use.
Disabled bindings
A disabled binding is ignored by the game, even when another mod would normally consume that key.
Config screen on F8
Pressing F8 in game opens a list of all bindings with buttons that switch each one between its states.
