   objSel.StartOfDocument(False)

   Position(vsStartOfLineOptions.vsStartOfLineOptionsFirstText, 4)  
   objSel.DeleteLeft(6)  
   objSel.DestructiveInsert("NEW TEXT")  
End Sub  

Sub Position(ByVal pos As vsStartOfLineOptions, ByVal ipos As Integer)  
   ' Moves the insertion point down to the beginning of the next line,   
   ' and then highlights the right-most four characters.  
   objSel.LineDown()  
   objSel.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstText)  
   objSel.CharRight(True, 4)  
End Sub  

Remarks

If the text selection is empty, then DeleteLeft deletes the indicated number of characters to the left of the active endpoint. If the value of Count is negative, then DeleteLeft performs like the Delete method.
