They're refering to Emoticons. Things like appearing as a yellowing smiling face, or appearing as a smiling face that is winking.
The users guide says that there is the ability to create preset messages. However, it does not give specific instructions on how. I believe it can be done under settings> messaging settings. At least that is what the guide says. Try it out. I don't have mine yet, waiting for shipping. Let me know if it works.
