I’ve never been able to find good documentation on filters and hooks. The best thing so far is to look in Adam Brown’s database, and see how/where they are called in the code.
It was from this that I found out that the ‘the_title’ hook is sometimes called with a post id, sometimes with a post object!
In this case, it looks like that hook only handles callbacks on fields already included in the Quick Edit, but I could be wrong…
