As opposed to the field-dirty-flag, which basically signals changes of a field compared to its state before entering mask edit state, the field-touch-flag provides the information, whether the active field has been changed compared to the state before entering the field.

When entering a field, the touch flag is always reset to zero. The information on a current change may only be requested that the Post_Field trigger. In the Pre_Field trigger the touch flag is undefined.
