"Can't you make it respond when the user presses the Send button or Enter?"

Yes, I suppose I could detect the Enter key, but the work needed to sink the button click would be more than I would think necessary for such a simple task (unless there's a particular bit about sinking the button click than I'm missing).

There isn't anything in the eventing structure of messenger to do this? I'm surpised that I haven't found anything in the docs I've read...
