And IIRC, Chrome copied this from Opera. It's a shame Opera never found its audience (or more specifically, a revenue stream), they pioneered a lot of browser features that we consider to be standard these days, like tabs and support for extensions.

It's been around in some form in most major browsers for decades. I remember Creating custom search entries in Firefox (or was it Phoenix still at that point?) in the early 2000's.
