I found an interesting item for Internet Explorer. Netscape has a wonderful plugin called Checky. I really should use Netscape more often. The closest IE comes is favlets. Some work… some don't… mileage varies. When it works you click on favorite item and it runs a javascript that validates your current page. I want my web pages to work so this makes it easy for me to test. It avoids a little key entry. The key issue is reading the errors and warnings the validator generates and clean them up.
