title: Modifying default tab size in RichTextBox
body: <p>Is there any way to change the default tab size in a .NET RichTextBox?
  It currently seems to be set to the equivalent of 8 spaces which is kinda large for my taste.</p>
  
  <p>Edit:  To clarify, I want to set the global default of "\t" displays as 4 spaces for the control.  From what I can understand, the SelectionTabs property requires you to select all the text first and then the the tab widths via the array.  I will do this if I have to, but I would rather just change the global default once, if possible, sot that I don't have to do that every time.</p>
