- * @fileoverview A patched, standardized event object for browser events.
- *
- * <pre>
- * The patched event object contains the following members:
- * - type           {string}    Event type, e.g. 'click'
- * - target         {Object}    The element that actually triggered the event
- * - currentTarget  {Object}    The element the listener is attached to
- * - relatedTarget  {Object}    For mouseover and mouseout, the previous object
- * - offsetX        {number}    X-coordinate relative to target
- * - offsetY        {number}    Y-coordinate relative to target
- * - clientX        {number}    X-coordinate relative to viewport
- * - clientY        {number}    Y-coordinate relative to viewport
- * - screenX        {number}    X-coordinate relative to the edge of the screen
- * - screenY        {number}    Y-coordinate relative to the edge of the screen
- * - button         {number}    Mouse button. Use isButton() to test.
- * - keyCode        {number}    Key-code
- * - ctrlKey        {boolean}   Was ctrl key depressed
- * - altKey         {boolean}   Was alt key depressed
- * - shiftKey       {boolean}   Was shift key depressed
- * - metaKey        {boolean}   Was meta key depressed
- * - defaultPrevented {boolean} Whether the default action has been prevented
- * - state          {Object}    History state object
- *
- * NOTE: The keyCode member contains the raw browser keyCode. For normalized
- * key and character code use {@link goog.events.KeyHandler}.
- * </pre>
