[Air-l] typos in chat

Does anybody know (or have any guesses about) the origin of using an asterisk to denote the correction of a typo in chat (and possibly other forms of CMC)? I.e.: SIDNEY: sounds god REBECA: I feel like i have some kind of goal now! SIDNEY: good* Thanks! -Kris -- ********** ********** ********** ********** Kris M.
