Event The Event object is the base class for any of the other event types, such as MouseEvent, ToolEvent and KeyEvent. Properties timeStamp The time at which the event was created, in milliseconds since the epoch. Read only. Type: Number modifiers The current state of the keyboard modifiers. Read only. Type: object See also: Key.modifiers Methods preventDefault() Cancels the event if it is cancelable, without stopping further propagation of the event. stopPropagation() Prevents further propagation of the current event. stop() Cancels the event if it is cancelable, and stops stopping further propagation of the event. This is has the same effect as calling both stopPropagation() and preventDefault(). Any handler can also return false to indicate that stop() should be called right after.
