There's a few of those out there... the Jetbrains ones have it, in addition (just off the top of my head from my 'collection') EditPlus, Komodo Edit, Aptana, Notepad++ (with plugin), PSPad, Crimson Editor, Caditor, Boxer... and I'm sure a lot more; that's just off the top of my head from the ones I've used. Not to say anything about the Blumentals editors- just that you have a few options if you're looking for that.
