Keycaps: 21kb (Classic Retro/Beige) keycaps are famous for being thick PBT, which is essential for that deep sound signature.

Layer 1: Media controls (Volume Up/Down, Play/Pause) and macro shortcuts. 3. "Katya" Specific Configuration
If "Katya" refers to a specific profile name or a character in a game (like Apex Legends or Warzone):
Macros: Set specific key combinations (e.g., Ctrl+Shift+K) to trigger in-game abilities or buy-menu scripts.
Lighting: Use RGB software (like OpenRGB) to set a "Katya" theme—typically associated with purple/pink or industrial grey aesthetics in the custom keyboard community. 4. Troubleshooting
Key Chatter: If keys double-tap, adjust the "Debounce" setting in your firmware.
Connection: Ensure you are using a data-sync USB cable; many "charging-only" cables will not allow the PC to recognise the custom pad.
