Key Features

75% layout offers most keys in a smaller footprint, saving desk space while retaining essential functions.
Customizable key functions and macros via the Keychron Launcher web app, enabling tailored workflows.

Trade-offs

Hot-swappable feature is only available on specific versions, so not all models support easy switch replacement.

Compact 75% layout omits a dedicated number pad, which may be less ideal for users needing extensive numeric input.
