Or better yet....
go to
www.bing.com
Right click in the search box and choose "add keyword for this search"
Enter a name, such as bing. Choose a bookmark place and enter 'b' in for the keyword.
Now when you want to do a search, simply enter 'b search term' into your address bar and it will automatically search bing for you.
You can use any name and keyword you want.
I use g for google, wiki for wikipedia, imdb for imdb, yt for youtube.... and so on and so forth and never have to use anything other than the address bar that is already provided for me.
