If you use Opera then you know that the default search engine that is used in the address bar is Google. To use another search engine, such as Bing, then you would type "b", and then your search term. So if I wanted to Bing my site I would type "b Techman's World". What some people do not know is that you can change the default search engine for the address bar. You will no longer have to rely on the search box, which will always have Google set back eventually from my own experiences.
