Thank you, now it works with this Workaround,

procedure TForm1.ccExecute(Sender: TObject);
  if FLastKeyPress <> nil then begin
      SynEdit1.OnKeyPress:= FLastKeyPress;

procedure TForm1.SetFocusAll;



but i have an other problems with SynCompletion , too

in the IDE i can type a 'c' or 'C' to select an item like 'Create', with
the Normal SynCompletion i have to use 'C' to select 'Create', someone
know something about this?

Best Regards,
