title: WinForms RichTextBox
body: <p>OK. Simple as possible: I want to inject a RichTextFormat comment (e.g. '{\*\atnid 1}' into the RichTextBox.Rtf;. That command doesn't show up in the richtextbox display area, which is the way I want it. The trouble is, there's no way I can see to put that comment in using C# and .NET. Adding it as a string adds an extra backslash each time, since the backslash char is the escape char, and the RTB displays it.</p>
  
  <p>How to get'{\*\atnid 1}' into the Rtf buffer without additional backslashes being added by .NET?</p>
