如何在Delphi中检测ctrl -t keypress

Question

I have a Win32 form with a TEdit control. When the user presses CTRL-t while the TEdit control is in focus, I want to detect it using the OnKeyUp event. I need a code example, please, using the Key and/or Shift variables. Thanks.

Set KeyPreview of the form to True, then write this code for OnKeyUp event of your form:

procedure TForm1.FormKeyUp(Sender: TObject; var Key: Word; Shift: TShiftState);
begin
  if (Key = 84) and (Shift = [ssCtrl]) then
    ShowMessage('Ctrl+t is pressed!');
end;
