You may not have heard of this command before; it's been sitting in the History menu for a while, but it hasn't ever made a huge splash. It lets you travel multiple pages in from a Google search result, and when you hit the end of the line and don't find what you need, you just use Search Results SnapBack to go right back to the last search results page. It's not as elaborate as the original version of SnapBack found in earlier versions of Safari, and it only seems to work with Google, but for my needs, it's very handy. If you combine the Command-Option-S shortcut with gleeBox (which we mentioned very recently) and Google's keyboard shortcuts experiment (I think you have to be logged in to access that), you can navigate an entire search session from the keyboard.
Granted, keyboard-only solutions aren't always faster than purely mouse-based solutions, and Web surfing is one area in particular where the mouse is generally the preferred tool. I'd probably be willing to challenge someone to a mouse vs. keyboard race sometime, but this is really a matter of preference more than speed. Of course, the Search Results SnapBack menu command is always available to mouse users.
We mentioned the SnapBack Extension, which recreates the original SnapBack functionality, back in August. The download page for the SnapBack extension seems to be offline, however, and I haven't had much luck with it recently, so I'll make do with the built-in feature for now.
