Catching a "character-typed" event in Outlook

I'm working on an Outlook addon and I'm wondering if there is a way to receive an event notification when a particular character, or set of characters, is typed? For example, say I want something to happen as soon as the user types '$' in a new mail item, is it possible to register for such an event?

Looks like there no events provided, that you can use. But you can try use Win32 API to get the key press event.
