The messages you need to trap are returnInField and enterInField.  
returnKey and enterkey are not sent to fields that are being edited.  
I'm not sure why. It's caught me out a few times.

Also, you may need to prevent users from pasting more than three  
lines into the field. For that, you could use the pasteKey message.
