This obviously only works if you have added the website to the bookmarks in either Firefox or Opera. When doing so you can add a keyword or nickname for that url which in turn makes it possible to access the website by typing in that keyword in the address bar.

Instead of accessing the website http://www.windows7news.com/ I simply type w7 and hit enter. The website loads just fine. Now, I do not recommend to add keywords for every bookmark that you have. This would surely lead to problems remembering the keywords for those urls unless you have a photographic memory.

I have about ten keywords for domains that I access regularly to speed up access. I do not add keywords for very short urls like cnn.com for instance but everything with 5+ chars makes sense. (it’s enough to enter cnn for cnn to enter the website in Firefox because Firefox will automatically load the first website in the Google results if no matching keyword was found.
