Interface Key
- All Superinterfaces:
 Serializable
- All Known Implementing Classes:
 KeyModifier
- Functional Interface:
 - This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
 
 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.
