I'm searching for this answer, too.
I realize that Q2A developers/contributors manipulate the CKEditor original scripts, and make it much more difficult to change.
Normally, you just need the textarea name/id and 2 scripts from CKeditor. Now they expand it into long lines of code, just for nothing, or for fixing the previous bugs.
Now, viewing the source code of yoursite.com/ask, the textarea has no name or ID?!
Instead, there are several lines of hidden inputs with name/id like
name="content_ckeditor_ok" id="content_ckeditor_ok"
name="content_ckeditor_data" id="content_ckeditor_data"
