4. Operating Instructions
4.1. Magic FN Key Functionality
The MAXFIT61 utilizes a 'Magic FN' key (Caps Lock by default when 'Magic FN' mode is active) to access secondary functions on the 60% layout. This allows for quick access to multimedia controls, function keys, and other commands without needing a full-sized keyboard.
To activate 'Magic FN' mode, press FN + Caps Lock. The Caps Lock key will illuminate to indicate 'Magic FN' mode is active. In this mode, pressing Caps Lock will act as the FN key, allowing you to use the secondary functions printed on the keycaps.
