Code:

private:
bool Key81Pressed;
bool Key87Pressed;
bool Key69Pressed;

--- CPP ---

Code:

__fastcall TForm1::TForm1(TComponent* Owner)
        : TForm(Owner)
{
   Key81Pressed = false;
   Key87Pressed = false;
   Key69Pressed = false;
}

void __fastcall TForm1::FormKeyDown(TObject *Sender, WORD &Key,
      TShiftState Shift)
{
   // 81=Q, 87=W, 69=E

   if ( !Key81Pressed && Key == 81 )
      Key81Pressed = true;

   if ( !Key87Pressed && Key == 87 )
      Key87Pressed = true;

   if ( !Key69Pressed && Key == 69 )
      Key69Pressed = true;

   if ( Key81Pressed && Key87Pressed && Key69Pressed )
   {
      Key81Pressed = false;
      Key87Pressed = false;
      Key69Pressed = false;
      ShowMessage( "Q W E Pressed" );
   }
}
void __fastcall TForm1::FormKeyUp(TObject *Sender, WORD &Key,
      TShiftState Shift)
{
   if ( Key == 81 ) Key81Pressed = false;
   if ( Key == 87 ) Key87Pressed = false;
   if ( Key == 69 ) Key69Pressed = false;
}

...ili pogledaj GetKeyboardState() API, ako ti ovo ne odgovara.

P.S.
Ili, gde god imaš u izrazima konstante tipa:
if ( Key == 81 ) Key81Pressed = false;
... zameni sa odgovarajućim velikim slovom zbog čitljivosti, na primer:
if ( Key == 'Q' ) Key81Pressed = false;
itd...

81 ---> 'Q'
87 ---> 'W'
69 ---> 'E'
