Ask HN: how do I save a HN story?

Hi,

I found this fantastic thing in my profile that is "saved stories" (http://news.ycombinator.com/saved?id=yourNick) and I hoped that that was the list of all upvoted stories... but it is not.

I have no idea how I "saved" some stories and I could really use a list of upvoted stories as a sort of local bookmark. I often find cool articles which I need to go back weeks/months later, but they're almost impossible to find.

Any help appreciated, thanks!
