title: Using KeyDown event in the parent window of a Delphi Mdi Application
body: <p>How do I get the KeyDown event to work in a Delphi (2007) MDI Applications Parent window, even if a Child window  has focus?</p>
  
  <p>I would like to implement a shortcut key (F1) that brings up a help screen in a MDI application, I have added the KeyDown procedure to the MDI Parent window and enabled KeyPreview in both the Parent and Child windows, but it does not work as expected.</p>
  
  <p>If I put a break point in the Parents KeyDown code I can see it never executes, even it there are no child windows open. But if I add the same code to the child window it works fine.</p>
  
  <p>Is there a way to get the parent window to receive the key presses, even if the child window has focus, as adding the code to 25+ forms seams a little wasteful?</p>
