+# W3C keyname
+
+Tiny library that exports a function `keyName` that takes a keyboard event and
+returns a
+[`KeyboardEvent.key`](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key)-style
+string. Will use the actual `key` property of the event if available,
+and fall back to a value synthesized from the `keyCode` otherwise.
+
+Probably often wrong on non-US keyboards, since the correspondence
+between a key code and the character it produces when shift is held is
+predicted based on a hard-coded table. Meant as a fallback for
+`KeyboardEvent.key`, not a replacement.
+
+The lookup tables from key codes (`event.keyCode`) to names are
+exported as `base` (when Shift isn't held) and `shift` (when Shift is
+held).
