This seems to happen quite often...
I have:
<h2>Download Our Catalog</h2>
Which needs to become:
<h3>Download Our Catalog</h3>
How would I go about writing a snippet/command that would allow me to select "<h2>Download Our Catalog</h2>", activate the snippet, and have the tag become selected ("h2" in this case) and mirrored in the closing tag, therefore allowing me to simply type "h3" and then tab back out?
