Discussion

This method is invoked when the user begins editing text in a control such as a text field or a form field. The control posts a textDidBeginEditingNotification notification, and if the control’s delegate implements this method, it is automatically registered to receive the notification. Use the key @"NSFieldEditor" to obtain the field editor from the userInfo dictionary of the notification object.

See controlTextDidEndEditing: for an explanation of why you may not always get one invocation of controlTextDidBeginEditing: for each invocation of controlTextDidEndEditing:.
