title: WM_KEYDOWN confusion
body: <p>I'm trying to get my application to do something when CTRL+S is pressed. I'm just not sure how the W and L params work for WM_KEYDOWN. MSDN has something about bit fields which i'm not sure about. How can I detect CTRL and S?
  Thanks</p>
  
  <p>What do I do if another control aside from hWnd has focus?</p>
