SendKeys.Send and turning off key modifiers

Question

I want to make ^N work the same as Down arrow in a tree control. I thought I'd just have to add the following to the KeyDown handler:

SendKeys.Send("{Down}");

but this gets treated as a Control-Down arrow since the control key is currently pressed. The msdn page describes how to turn on the control modifier but not how to turn it off.

Thanks, Keith

Sorry to come late to the party but I think I found a solution:

First, import SetKeyboardState:

[DllImport("user32.dll")]
public static extern bool SetKeyboardState(byte[] lpKeyState);

Then, just call it with a zeroed byte array before calling SendKeys.Send():

SetKeyboardState(new byte[256]);
SendKeys.Send("your key sequence");

That worked for me. Hope this helps!
