simple keyDown testcase no worky

[Brannon]

In the following code I have a Control in a UserControl in a Form. The
Control always gets the keypresses, even after I call Select on the
UserControl. What's the right way to do that? I actually want the
UserControl to get all keypresses and make the Control just pass its
presses to its parent. Thanks for your time.

I was able to make it work by making the Control not selectable. I
still think there should be a way to support both key handlers, though.
