Plug in, open launcher.keychron.com in your browser, and the F4 is ready to configure — no download, no driver. Choose a ready-made preset for codex or claude and go, or remap the keys, record macros, and set how far each key travels.
The codex and claude presets each include a key for voice input. Prefer to just say it? The built-in AI assistant sets keys up from a plain-language request.
*The F4 does not have a built-in microphone. For voice input, use your computer's built-in microphone or an external microphone.
