I'm not convinced, yet. As eCompletion never changes the source while it is open. Only when accepting an entry in the
menu, the choice gets inserted. But then the menu (listing of entries) is closed. But then the user discovers he has 
choosen the wrong entry. Suppose he could press an Key and re-open the menu pointing at the choosen entry and replace
it with another entry? Would that solve the problem?
