How to break out a top DIV?

I'm looking around the web for a simple, yet useful WYSIWYG editor and so far CKSource looks ok for my needs, however I have one little problem. If I insert a DIV at the very beginning of the editor (http://ckeditor.com/demo) I can't break out of it, I mean type text before that div. How can I break out of the damn div? Thanks!
