I got into a little trouble sending keys. It seems like when ever I want to send keys It doesn't work.
I'm thinking about sending alphabetic characters such as T to bring the chat up from example, but If I write It to the enum, nothing happens whenever I use them. Any ideas?

public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);
[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
