Send keys in FNC under FMX

Hi,


I have a search edit that has a TtmsFncResponsiveList underneath it.  I would like to send the arrow keys and the enter key to the responsive list without leaving  the edit as I type.  In the VCL I could use TWinControl.Perform for this from the edit's onkeydown but how would I do it in FMX with the responsive list?



procedure TfrmMain.edtSearchStockpilesKeyDown( Sender: TObject; var Key: Word; var KeyChar: Char; Shift: TShiftState );
begin
  tmslogger.Info( Key );
  case Key of
    vkPrior: actStockpilesUpExecute( Sender );
    vkNext: actStockpilesDownExecute( Sender );
    vkLeft: lstStockpiles. ???;
    vkUp:;
    vkRight:;
    vkDown:;
    vkReturn:;


  end;
end;


Many thanks

Steve
