Table of Contents

Is there a way or a setting that makes the table of contents close when you move your mouse away from the table of contents without having to click anywhere to make it close? I would like to make my TOC have sort of a hover feature. I watched a Paul Wilson video and changed the action for "on enter" to hide TOC and that will make the TOC disappear when you click on a certain section in the TOC but you still have to click on something to make the TOC disappear.
