marijnh/w3c-keyname

W3C keyname is a tiny library that provides a `keyName` function to return a `KeyboardEvent.key`-style string from a keyboard event. It prioritizes the actual `key` property if available, and falls back to a synthesized value from `keyCode` using hard-coded lookup tables. This library is intended as a fallback for environments where `KeyboardEvent.key` is not supported, though it may be less accurate on non-US keyboards.
