When you do a search, often times you want to go back to the search results to select another link. I just found out in Safari you could do what they called it “search results snapback”, the shortcut is command-option-S, it brings you back the the search results. Very handy.
You can also mark a page for snapback with command-option-K, and to snapback to it use command-option-P, or you can use the History pull down menu…
