where to add a key and text pair? in the your option section there is only details and permissions, no place to add pair.

This is a great Add-on within Firefox. As long as you follow the directions and push "CTRL" and period "." at the same time right after your key, it works every time. I love the new date and timestamp feature which is easily implemented by adding [[Now]] in the text for any key. Thank you for putting the time and effort in to this Add-on.
