Seriously, only an actual <CR> forces the action method. This is a Bad  
Thing, because I have watched many users not bother to hit any field  
movement key after t hey finish typing in a field. If the next thing they  
hit is the Save button, the last field never gets a chance to validate.  
IMHO, any inter-field movement should trigger the action method.

For what you want, the Matrix which contains the FormCells must have a  
text delegate, and you must use the text delegate methods (textWillEnd:,  
textDidGetKeys:, etc.) to validate as they type. Even with this procedure,  
the delegate methods seem to jump off at different points depending on  
whether the keyboard or the mouse was used to instigate the field  
movement. Bottom line, the action method is not reliable.
