title: Allow user to use tab in RichEditBox in a Windows 8 App?
body: <p>Right now the tab function moves the focus to the next control, I want it so it just actually tab in the Text Box.</p>
  
  <p>I noticed you cannot tab in the Windows 8 Mail app also....</p>
  
  <p>Also is there a RichTextBox alternative?</p>
