You can do some hacky stuff with onClick listeners for links, especially if its a single page. That said, I do not do this. But I don't think I use much beyond div, span, a, ul, li, table (and friends), form (and crew), h1-6, script, body, head, and html. I know there are more HTML tags, but I rarely use them. They are all pretty self explanatory, and I have hard time believing the author looked at 80 pages and everyone used the wrong tags.
