TinyMCE Find and Replace?

System

Hello,
I am investigating a way to find and replace specific text in the TinyMCE (Tinymce 3.1.1 ) HTML Source Editor in TeamSite (6.7.2, service pack 1) .

I found a post in the TinyMCE forums which suggested the use of Christophe Dolivet's EditArea
Has anyone tried to implement EditArea (http://www.cdolivet.com/index.php?page=editArea&sess=9f0491e1255ef83cf7a1856d69d2ed17)

in TeamSite?
Thank you.
