How I'm imagining this could work: - If the beginning of the selected text is on or immediately after a `[starting]` tag, delete it and create a new `[starting]` tag...

Tricky. I don't know how this should behave if the user selects something that spans several tags, spans more closing tags than opening tags, etc.

Hey thanks for the request, I'll see if any med mains have a template they want to PR.

Just needs a psych eval template now.
