You can easily flip through your messages using the "Next" and "Back" buttons to move to the next (an older) message, and previous (a more recent) message.
You are also able to print messages. While your message is opened, click the "Print" button. This will allow you to print any message in your inbox.
When you decide it's time to leave the message, press the "Close" button and it will take you back to the Message Center Inbox.
