/**
 * Binds keycodes to actionnames in an editor.  This aggregates an internal {@link handler} and extends the implementation of {@link mxKeyHandler.escape} to not only cancel the editing, but also hide the properties dialog and fire an <mxEditor.escape> event via {@link editor}.  An instance of this class is created by {@link mxEditor} and stored in {@link mxEditor.keyHandler}.
 *
 * @Example
 * Bind the delete key to the delete action in an existing editor.
 * ```javascript
 * var keyHandler = new mxDefaultKeyHandler(editor);
 * keyHandler.bindAction(46, 'delete');
 * ```
 *
 * @Codec
 * This class uses the {@link mxDefaultKeyHandlerCodec} to read configuration data into an existing instance.  See {@link mxDefaultKeyHandlerCodec} for a description of the configuration format.
 *
 * @Keycodes
 * See {@link mxKeyHandler}.
 * An {@link mxEvent.ESCAPE} event is fired via the editor if the escape key is pressed.
