An event handler property for right-click events on the window. Unless the default behavior is prevented (see examples below on how to do this), the browser context menu will activate (though IE8 has a bug with this and will not activate the context menu if a contextmenu event handler is defined). Note that this event will occur with any non-disabled right-click event and does not depend on an element possessing the "contextmenu" attribute.
The hashchange event is fired when the fragment identifier of the URL has changed (the part of the URL that follows the # symbol, including the # symbol).
