Each day I learn something new on my Windows Phone.  I have a lot of contacts and I was getting tired of scrolling to a name or searching.  I hit a button my accident and found a quicker way to get to a name in my contact list.

In the list of contacts there are squares with a letter sort of like a rolodex.  If you tap any of those letters you can jump to a particular letter in the alphabet.
