The default Sublime install doesn't have very many HTML snippets. When I'm working on an HTML or PHP doc and I type "div" and press TAB a snippet gets run like this:
<div>$1</div>
I want to make some changes to the snippet, but as I'm looking through the folders, I can't find any DIV snippets anywhere. Its definitely not in the HTML or PHP folder. How do I tell where it is so I can make changes?
