If you don't know about Ctrl-Enter in the address bar or your web browser I encourage you to try it out. If you type "cnn" and then hit ctrl-enter it will prepend the "www." and append ".com" so you have "www.cnn.com" which is great!
Just today I got a Starbucks gift card and I wanted to see the balance on the card and to do so I would need to go to "www.starbucks.com/card" as it was printed on the back of the card. I had already opened Firefox and I typed starbucks in the address bar and at this point I would go through the effort to hit home type www., hit end type .com and then "/card" but instead I just typed "starbucks/card" and I hit Ctrl-Enter and Firefox filled in the rest for me so I went to www.starbucks.com/card. It was just too awesome.
I tried it again, for example the OneNote site is: www.microsoft.com/office/onenote/ so I just typed "microsoft/office/onenote" and Ctrl-Enter and it went to the right site! Sadly this doesn't work in IE 7 : ( However I was just very pleased to see this feature working and just how I would try it too!
