Or a ctrl-click (and a tool-tip to that effect,) rather than just a click, when in edit mode, so that you don't accidentally launch the site, when all you wanted to do was position the insertion bar inside the word or url.
Also, how about activating the link as soon as it is recognized as one, assuming it is entered like { Link }
I'm voting yes with the provision that it's a Ctrl+Click option. As @2 mentions, if all you wanted to do is add/change a character, clicking on the URL will be a little problematic.
