KeyLens
by caju
KeyLens puts a search bar on the vanilla Controls screen, so players can filter keybinds by typing part of a name, category or key.
What it does
Typing into the search field narrows the keybind list at once, and the vanilla Controls screen keeps its usual layout and flow. Fuzzy matching accepts short or partial input, so a few letters can find a binding without the full name. Prefix searches such as category:movement, name:jump or key:space narrow results by one specific field.
KeyLens requires Fabric API and runs on Fabric for 1.21.11 only. It is client-side only, so only the client needs it and servers can run without it. Latest file is 1.0.1 for 1.21.11, released 2026-05-24, and the mod is released under the MIT License; it is open source, with public source code and an issue tracker.
Key features
Search on the Controls screen
A search bar is added directly inside the existing Controls screen, with no separate menu to open.
Instant keybind filtering
Results update while typing, so a binding can be found without scrolling through the full list.
Fuzzy matching
Short partial inputs still match keybinds, which helps when the exact name is not remembered.
Prefix-based queries
Queries such as category:movement, name:jump and key:space limit matches to a chosen field.

Use cases
Large keybind lists
Players with many mods installed can locate a binding quickly instead of scrolling past every category.
Finding a key by its binding
Searching by key, such as space, shows which action is assigned to it.
Who it’s for: Players on Fabric 1.21.11 with many keybinds from mods, who want to locate a binding without leaving the Controls screen.
How it compares
Drop Keybinds is open source under the Apache License 2.0 and runs on Fabric for 1.21 – 1.21.8, so it does not cover 1.21.11. Searchable Packs is released under the MIT License for 1.21.4 – 1.21.8, while Fuzzy Cmd is all rights reserved and targets 1.21 – 1.21.1. KeyLens covers 1.21.11 only, is client-side only and is open source under the MIT License.
