KeyCode class abstract

Defines the keycode values for keys that are returned by KeyboardEvent.keyCode.

Important note: There is substantial divergence in how different browsers handle keycodes and their variants in different locales/keyboard layouts. We provide these constants to help make code processing keys more readable.

Constructors
