Sometimes, it seems like there must be more to life than typing "www" and com" repeatedly and endlessly. Here's a quick tip to give your fingers a rest and increase accuracy at the same time.
If the URL for the website you are visiting is http://www.website.com, just type "website" and then, while pressing on Ctrl, press on Enter. "http://www." and ".com" will be automatically added before and after the website name.
Oh yes, if you want to impress your friends, you can tell them that URL stands for Uniform Resource Locator.
One more thing, there is no need to type "http://" at the beginning of the URL. It is the default prefix if nothing else is entered.
