@FunctionalInterface
public interface Key
extends Serializable
```
An interface to represent keyboard keys.
While the Key values defined here consist of multiple values in order to account for variability in browsers, the Key values that come from the client only consist of the single value known to the client's Browser.
Some of the Key values map only to event.key values while other Key values contain values for both event.key and event.code, and some only contain a event.code value. In cases where a Key containing only event.code value is a subset of a Key based on event.key value, the event.code is included in the latter Key only.
For example, Key ALT consists of values [Alt, AltLeft] and ALT_LEFT is a key itself. See the documentation of the Key instance for more information about its relation to event.key and event.code values.
See https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values for event.key values and https://w3c.github.io/uievents-code/ for event.code values.
