title: RichTextBox equivalent of TextBox.AcceptsReturn
body: <p>I am switching several TextBoxes out for RichTextBoxes to gain some of the cool features.</p>
  
  <p>I had my TextBoxes configured to AcceptReturn so that the enter key will create a new line, rather than leave the control. The RichTextBox does not seem to have this feature.</p>
  
  <p>Is there a simple way to do this, or do I have to capture all keypresses and handle them individually?</p>
