shiftKey property

shiftKey
The KeyboardEvent.shiftKey read-only property is a
boolean value that indicates if the shift key was pressed
(true) or not (false) when the event occurred.
The pressing of the shift key may change the KeyboardEvent.key of the
event too. For example, pressing B generates key: "b", while
simultaneously pressing Shift generates key: "B".
Implementation
external bool get shiftKey;
