For those of you that like to save as many keystrokes as possible, here is something that you'll love. You can enter any string of characters in an address bar and then press Ctrl-Enter. Windows will automatically add both the “www.” and the “.com, and then search for the page on the internet.
For example, if we type pctlc in an address bar and then press Ctrl-Enter, Windows will take us to www.pctlc.com.
Try for yourself!
