David, gracias

No es del ENTER porque siempre lo utilizo para pasar de un campo al otro. Mi código del evento OnKeyPress es

Código Delphi [-]
procedure TBookingFrame2.FormKeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
   case Key of
     VK_UP     :
       begin
         SelectNext(Sender as TWinControl, False, True );
         Key := 0;
       end;
     VK_DOWN   :
       begin
         SelectNext(Sender as TWinControl, True, True );
         Key := 0;
       end;
     VK_PRIOR, VK_NEXT :
       If not Panel2.Visible then
         Panel1.SetFocus
       else
         DBGridRL1.SetFocus;
     VK_RETURN :
       If Shift = [ssCtrl] then begin
         Key := 0;
         If (Sender = EditDB1) or (Sender = EditDB2) or (Sender = EditDB3) then
           ToolButton1Click(Sender);
       end;
   end;
end;
 
procedure TBookingFrame2.FormKeyPress(Sender: TObject; var Key: Char);
begin
  If Key = #13 Then begin
    If HiWord(GetKeyState(VK_SHIFT)) <> 0 then
      SelectNext(Sender as TWinControl, False, True )
    else
      SelectNext(Sender as TWinControl, True, True );
    Key := #0;
  end;
//  If (Sender = EditDB1) or (Sender = EditDB2) or (Sender = EditDB3) then
//    Key := #0;
end;
