Home-button is a good trick to know about but I wish there was an easy way to jump between the top and the location I came from to get back. It seems back-button does not do that on my browser at least. Since browser's don't do it there could be a side-ribbon that had a TOP-button and then a BACK-button. I think that would be useful on sites like HN.
