Smiley: a colloquial term for a small symbol, made out of ordinary characters but often representing a smiling face, inserted into an e-mail or news article to indicate that a message or comment is humorous, ironic, or not meant to be taken seriously!!!
We use Smileys almost on a daily basis – be it over IM convos, Bulletin boards or discussion boards or even in plain email communications. Now whilst Yahoo! and MSN have a niche set of smileys, Google Talk does not have any dedicated ones i.e. there is no emoticon or smiley toolbar from wherein smileys can be added onto the IM’s. But it does have some in-built smileys that can be typed in via the keyboard as common key-combos and which automatically get transformed into animated smiley icons. Now everyone might be knowing about the commonly used smileys like the smile [:-)] or the frown [:-(] but GTalk has a few more smileys that can be used via the keystroke combos. Here is a pic showing the GTalk Smileys and the key-strokes to be used for getting them:
