/**
* The KeyboardEvent interface provides specific contextual
* information associated with keyboard devices. Each keyboard event
* references a key using an identifier. Keyboard events are commonly
* directed at the element that has the focus.
* The KeyboardEvent interface provides convenient attributes
* for some common modifiers keys: KeyboardEvent.ctrlKey,
* KeyboardEvent.shiftKey, KeyboardEvent.altKey,
* KeyboardEvent.metaKey. These attributes are equivalent to
* use the method
* KeyboardEvent.getModifierState(keyIdentifierArg) with
* "Control", "Shift", "Alt", or "Meta" respectively.
*
To create an instance of the KeyboardEvent interface, use
* the DocumentEvent.createEvent("KeyboardEvent") method call.
