Earlier quoted context omitted.
Chrome offers this quiet magical feature called ‘tab to search’, Firefox allows you to make custom search key shortcuts but you need to make each of them. It’s just not as easy to use and is a killer feature that’s very fast/useful and missed for anyone who uses it and tries to switch away to Firefox. It’s the only thing that keeps pulling me back to Chrome, as well as many others I’ve seen discuss it in forums over…
I just have duckduckgo as my default search engine, that way I can use the bangs to search almost any site that's even remotely mainstream by starting my search with !w (wikipedia), !y (youtube) !hn (hacker news), !g (google), etc.
You can add things like YouTube etc as well so long as they have "OpenSearch" metadata. (Presumably what Chrome is using for "tab to search"?) [1]
