Summary ✨

This C++ code defines a mapping of keyboard keys to their corresponding virtual key codes, which are used by the operating system to recognize and process keyboard input. The mapping includes standard keys, function keys, navigation keys, and special keys such as delete and insert. It is likely part of a larger project that requires custom keyboard handling or emulation.
