    <div contenteditable="true" id="content">...</div>
...
CKEDITOR.inline( 'content' );

}, anotherObject );

someObject.on( 'someEvent', function( event ) {
    alert( event.listenerData );        // 'Example'
}, null, 'Example' );

someObject.on( 'someEvent', function() { ... } );                       // 2nd called
someObject.on( 'someEvent', function() { ... }, null, null, 100 );      // 3rd called
someObject.on( 'someEvent', function() { ... }, null, null, 1 );        // 1st called
