"If you've used an instant messenger or chat service, you've seen the ubiquitous smiley and frowning faces used to represent happy and sad. These symbols are called emoticons, a combination of the words "emotion" and "icon," and you can insert them to add a personal touch to most Office documents.
Note In a purely unscientific poll of the Office Online team, we couldn't agree on what the third symbol meant. Different people thought that it was a sign either of indifference, frustration, or grumpiness. You be the judge. MSN® Messenger officially calls it disappointed, so we'll use that description for this article."
