Emoticons are graphic images that you can use to express emotions within an instant message conversation.
Do any of the following:
Add an emoticon to a message
In the conversation window, click .
Click the emoticon that you want to use, and then press ENTER.
To turn off emoticons, on the Communicator menu, click Preferences, and then click Appearance. Under Message Font Style, clear the check boxes for the emoticons that you don't want.
Depending on a contact's messaging application and messaging service, custom emoticons and some standard emoticons might not be visible to that contact.
