Trigger to close an object when tab focus moves from it?

Thanks for looking into this and letting me know, Tom.

Yeah, I ended up programming it with the Enter key and have included an instruction about it on our keyboard instructions lightbox page. I considered adding a close button or X icon, but felt that would clutter up the trigger list and tab order list too much (resulting in about 36 items instead of 18). Many thanks again for your help and advice!
