Many of you may already be familiar with this shortcut, so this is for those who aren’t. For websites that end in .com, you can type the name of the website (gmail or yahoo) in the address bar and press Ctrl + Enter, and the browser (works in Opera, Firefox, IE) will complete the address for you.
So, for example, if you wanted to access the CNN website, instead of typing http://www.cnn.com/ (or http://www.cnn.com/), simply type cnn in the address bar and press Ctrl + Enter. The browser will complete the address and take you to the website, in this case http://www.cnn.com/.
The drawback of this method is that you can’t access websites ending with other suffixes like .in, .net, .org*, etc. Still, since many websites end with a .com suffix, this is a handy shortcut to remember. It’ll save you from typing a few extra characters, which is a good thing for your fingers.
*: If you’re using Firefox, however, this How To Geek article will tell you how to automate .net and .org address.
