* @param {String} eventName The name of the event that will be listened to.
* @param {Function} listenerFunction The function listening to the
* event. A single {@link CKEDITOR.eventInfo} object instance
* containing all the event data is passed to this function.
* @param {Object} [scopeObj] The object used to scope the listener
* call (the `this` object). If omitted, the current object is used.
* @param {Object} [listenerData] Data to be sent as the
* {@link CKEDITOR.eventInfo#listenerData} when calling the listener.
* @param {Number} [priority=10] The listener priority. Lower priority
* listeners are called first. Listeners with the same priority
