}

Represents the location of a physical key.

This mostly conforms to the UI Events Specification’s KeyboardEvent.code with a few exceptions:

• The keys that the specification calls “MetaLeft” and “MetaRight” are named “SuperLeft” and “SuperRight” here.
• The key that the specification calls “Super” is reported as Unidentified here.
• The Unidentified variant here, can still identify a key through it’s NativeKeyCode.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unidentified(NativeKeyCode)

This variant is used when the key cannot be translated to any other variant.

The native keycode is provided (if available) so you’re able to more reliably match key-press and key-release events by hashing the KeyCode. It is also possible to use this for key-binds for non-standard keys, but such key-binds are tied to a given platform.
