sublime - how to save file on close automatically
===

How do I configure Sublime 2 to save files automatically that I close? It should behave like, User opens file, makes edits, closes file, and the edits are automatically saved even though the user did not manually save the edited file.  

This is close, but I want it to save on file close rather than lose focus.
