Un ejemplo rápido:

delphi

unit Unit4;
 
interface
 
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs;
 
const
  ID_HOTKEY = 100;
 
type
  TForm4 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
    procedure WMHOTKEY(var Msg: TMessage); message WM_HOTKEY;
  public
    { Public declarations }
  end;
 
var
  Form4: TForm4;
 
implementation
 
{$R *.dfm}
 
procedure TForm4.FormCreate(Sender: TObject);
begin
  RegisterHotKey(Handle,ID_HOTKEY,MOD_CONTROL,Ord('K'));
end;
 
procedure TForm4.WMHOTKEY(var Msg: TMessage);
begin
  case Msg.WParam of
    ID_HOTKEY: ShowMessage('Hola');
  end;
end;
 
end.

...Y si lo que realmente quieres es un Hook al teclado, puedes encontrar ejemplos en 1, 2, 3 y 4 (estos 3 últimos mas reservados)

Claro que todo esto es exclusivo para Windows

Saludos.

Informacion adicional para este tema. Ya se que el Hilo es Viejo...

Hooking into the Windows API is a complicated process and there are several techniques to achieve this. Microsoft recommends that the callback procedure for most hooks should reside within a DLL, this is the method used by the TCPKeyHook Component. The Component encapsulates the procedures and functions within the separate DLL and uses Memory Mapped File (MMF) to send a custom message with the keyboard information to the calling application or process. The result is a system wide hook into all global keyboard events generated by the user keyboard input.
