Well yeah, that's what I was referring to in my original post. That seems to be the only solution, I was just wondering if maybe a lesser known keyword or possibly a workaround existed which would take a user to the top of a page without referencing an id associated with an element.
The link or id method is safer-- unfortunately re-loading the page often forces people back to the top of the page. This sucks using JAWS because if you're on one of those silly AJAX pages where stuff gets updated and reloaded all the time, you keep getting sent back up to the top of the page.
People also have their own keyboard shortcuts to the tops and bottoms of the page and you wouldn't want to interfere with those either.
Plus with a link you can explicitly warn people: "this will take you back to the top of the page!" Getting jerked up unexpectedly to the top of the page is disorienting enough (like target="blank" opening new windows unexpectedly).
