"Wrap with" or "Surround with" Feature for Text Selection

I've been loving Postico, but there's this one feature that I've been missing, and I bet I'm not the only one.

A "wrap with" or "surround with" feature in the editor. Like, if I highlight example and press the " key, it becomes "example". Currently in Postico the selection is replaced with the ".

I've gotten so used to this in other IDE. It's one of those things that once you've had, it's hard to live without. A lot of IDEs out there have this feature, and it's a time-saver. Would be awesome to see it in Postico too.

No files, tests, or entry points are named. Begin by locating the editor behavior for selected text and quote-key input; done means surrounding the selection with the typed quote instead of replacing it, while preserving the existing editor behavior for unselected text.
