I had another of these "duh!!!!" moments.
I was scrolling down my list of contacts. One by one, down the list trying to get the the letter M. I have always done it this way. After all when I first started the list was not all that long. But the list has grown until now it is rather long.
I accidentally pushed the "2" and I found myself back in the "A's". Pushing the 6 put me in the "M's".
Oh dear! Another secret of the universe has been unlocked!
