At least once a week, I run into a situation where I want to revisit a site I had visited earlier but forgot to bookmark or didn't even think of bookmarking. All I can remember is a part of the page's title. Wouldn't it be nice if there was a slick tool that would allow you to quickly search your browser history? I was all ready to fire up XCode when I discovered that the Safari team had already thought of this.
Simply hit Cmd-Option-B and type something in the little search field in the bottom of the window.
Could maybe be a tad quicker (without having to click to focus on the search field), but a really useful feature nonetheless.
