+/**
+ * Provides extended keyboard support for the "contextmenu" event such that:
+ * <ul>
+ * <li>The browser's default context menu is suppressed regardless of how the event is triggered.</li>
+ * <li>On Windows the "contextmenu" event is fired consistently regardless of whether the user
+ * pressed the Menu key or Shift + F10.</li>
+ * <li>When the "contextmenu" event is fired via the keyboard, the pageX, pageY, clientX and clientY
+ * properties reference the center of the event target. This makes it easy for "contextmenu" event listeners
+ * to position an overlay in response to the event by not having to worry about special handling of the x
+ * and y coordinates based on the device that fired the event.</li>
+ * <li>For Webkit and Gecko on the Mac it enables the use of the Shift + Control + Option + M keyboard
+ * shortcut to fire the "contextmenu" event, which (by default) is only available when VoiceOver
+ * (the screen reader on the Mac) is enabled.</li>
+ * <li>For Opera on the Mac it ensures the "contextmenu" event is fired when the user presses
+ * Shift + Command + M (Opera's context menu keyboard shortcut).</li>
+ * </ul>
+ * @module event-contextmenu
