 You have all of the custom meta boxes as well. A user might want to change
 a metabox field. How would you handle that? Each metabox works
 differently.

 Yes, a post ''is'' more than the main content editor. But all those other
 fields fall inside the `form` element with id of `post`, so the jQuery
 selector `form#post` should encompass all those fields.

 Navigate to the edit screen for a post. Then Open your javascript console
 and paste this:
 `jQuery('form#post, #content').change( function(){  console.log( 'change
 detected' ); });`
 Then start changing stuff. Almost anything triggers a change. What doesn't
 work is the post content editor. It would take some figuring out but it
 should be fairly simple.

 What isn't simple: figuring out if this is a good idea or not. What's the
 benefit to disabling the save button?
