4. Functionality
The Kbd-UK functions as a layout-specific keyboard configuration that defines the physical and logical arrangement of keys for British English input. It is designed to be integrated into Rayon’s modular keyboard systems or used as a selectable layout option in configurable keyboards.

How It Works:
- The layout defines the physical key positions and the corresponding character mapping recognized by the operating system.
- When installed, the keyboard communicates with the host device via USB or wireless interface (depending on the base model).
- The firmware identifies the layout as “UK” and ensures that all keypresses correspond to the correct British character set.

Use Cases and Applications:
- Professional Environments: Offices, data entry, and administrative work requiring UK-standard input.
- Educational Institutions: Schools and universities in the UK or Commonwealth regions using British English.
- Software Development: Ideal for developers and IT professionals working with UK-based systems or localization projects.
- Government and Public Sector: Ensures compliance with regional input standards for official documentation.
- Consumer Use: Suitable for home users preferring the UK layout for typing accuracy and familiarity.

Compatibility:
- Compatible with all major operating systems (Windows, macOS, Linux, ChromeOS).
- Works with Rayon’s modular keyboard platforms and other systems supporting ISO UK layouts.
- Supports plug-and-play recognition without additional drivers.
