// Be careful not to hook up any of the text fields' actions to update: because we handle them in controlTextDidChange: instead.  If we could get the active text field somehow via public API (guess we could use controlTextDidBegin/controlTextDidEndEditing) then we'd not need to overload the update sender for this purpose.  Or, I guess, we could use another method other than update.  It should not be this hard to implement what is essentially standard behavior.  Sigh.
// Note: finding out whether a given control is editing is easier.  See: <http://cocoa.mamasam.com/COCOADEV/2002/03/2/28501.php>.
