Make the Save button use a custom script

I've looked all over. Found many people with all sorts of answers, except the one most people are asking. Maybe we're asking it wrong? Let me try again.

Question 1) If I am not wrapping the editor in a FORM tag, what must I do to make the save button appear and be active anyway?

Question 2) I want to save my data that is in my editor using ajax, but I also want to make use of the Save button in the editor. How do I change it so that the Save button in the editor will call a javascript function? Keep in mind, I am NOT wrapping a form tag arond the editor.

Thanks in advance for your help.
