WHIZZYWING
 is a lightweight (7k gzipped) WYSIWYG rich text editor in JavaScript. It replaces elements such as textareas with a contenteditable (as per HTML5) div with a tailorable formatting toolbar. It returns sane HTML into the replaced element. It works in modern desktop browsers - including Chrome, Firefox, Safari, Opera, Chromium - with contenteditable support and Internet Explorer from IE6 onwards.
 
KNOWN ISSUES:
 Full screen option not available in IE6.
