Greetings. After reviewing most current eReader offerings I stumbled back to the Nook as the latest upgrade came out. I was sold. I've had mine a few weeks now and really enjoy it. I do have one question that someone may be able to answer....

I often manage to get the letter "K" in a band of highlight on the lower display and have never figured out what it means or how I caused it. Gotta be something I've failed to read int the instructions.
