How to 'undo' automated Emoticons

I am running WLM Version 2012 (Build 16.4.3528.0331).

I don't want to disable the automated Emoticons feature in WLM, but how do I undo this feature on a 1 by 1 basis in each email? Certain combinations of letters & symbols automatically insert an Emoticon at the cursor point - '(s)' inserts a half moon, for instance. How do I revert to '(s)'?
