How Super User (and probably all Stack Exchange sites) handle clicks to preview areas for posts currently being written is confusing and horribly inconsistent:

* **If I click the preview pane for a new answer...**

  The page focuses on the associated answer text area, i.e. the input field that is used as source for the preview I just clicked.

  *Very useful for longer posts, especially in topics with several answers, since it makes finding the text field trivially easy*.

* **If I click the preview pane for an existing post I'm editing inline...**

  Nothing happens. The current text area loses focus.

* **If I click the preview pane for a [Q&A style answer](https://meta.superuser.com/questions/4882/answer-your-own-question-surely-you-jest-what-next-fix-my-own-plumbing) written parallel to the question...**

  The page focuses on the text area *for the question?!*

  *Surely you jest! What's next, focusing the search box?*
