Emoticon
In web forums, instant messengers and online games, text emoticons are often automatically replaced with small corresponding images, which also came to be called "Emoticons." Similarly, in some versions of Microsoft Word, the Auto Correct feature replaces basic smileys such as :-) and :-( with a single smiley-like character. Originally, these image emoticons were fairly simple and replaced only the most straightforward and common character sequences, but over time they became so complex that the more specialized emoticons are often input using a menu or popup windows, sometimes listing hundreds of items. Emoticons have also expanded beyond simple cartoon facial expressions to a variety of still or moving images. Some of these graphical emoticons do not actually represent faces or emotions; for example, an "emoticon" showing a guitar might be used to represent music. Further, some instant messaging software is designed to play a sound upon receiving certain emoticons.
