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 they finish typing a field. If the next thing they hit  
is the Save button, the last field never gets a chance to validate.

For what you want, the matrix which contains the FormCells must have a  
text delegate, and then you must use the delegate methods (textWillEnd:,  
textDidGetKeys:, etc.) to validate as they type. Even with this procedure,  
the delegate methods seems to jump off at different points depending on  
whether the keyboard (Tab, Shift-Tab, etc.) or the mouse is used to  
trigger the next field. The bottom line is, only textDidGetKeys: and  
textDidEnd: are reliable indicators of keystrokes and field movement under  
all circumstances.
