Shortcut Icon - the little image next to the url in the menu bar

The others, for UAs that support it, provides a menu bar in the browser.
I know that Opera supports it, and Firefox with an extension. I'm sure

previous document in a group of documents, next, next document, etc.
This information can also be useful for search engines.
