KeyboardEvent: shiftKey property
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 key
of the event too. For example, pressing B generates key: "b"
, while simultaneously pressing Shift generates key: "B"
.
