This is an example for COPY. Figure out what it does and do the same for cut and paste. write the following:

procedure TForm1.FormCreate(Sender: TObject);
begin
  Application.OnMessage := AppMessage;
end;

procedure TForm1.AppMessage(var Msg: TMsg; var Handled: Boolean);
begin
if (Msg.hwnd = edit1.Handle) and //if the focus is in the edit1
   (Msg.Message=WM_KEYDOWN) and //if the user pressed a key
   ((Msg.wParam = 67) OR (Msg.wParam = 99)) then //if C or c was pressed
begin
    if GetKeyState(VK_CONTROL) < 0 then  //if control key is down            
    showmessage('copy is canceled');
    Handled := True;//cancel the copy action
end;
