Failing that, what's the best way for an app to respond to a global key press? i.e. whatever app has focus, when the user press X do this.

I started with WM_Paste, but my app never receives that message, only WM_DrawingClipboard. I think because its not the target of the paste.

public class MyTextBox :TextBox
  {
      const int WM_PASTE = 0x302;

      protected override void WndProc(ref Message m)
      {
          if (m.Msg ==WM_PASTE)
          {
              MessageBox.Show("WM_PASTE was fired");
          }
          base.WndProc(ref m);
      }
  }
