title: How Do I detect Text and Cursor position changes in Word using VSTO
body: <p>I want to write a word addin that does some computations and updates some ui whenever the user types something or moves the current insertion point. From looking at the MSDN docs, I don't see any obvious way such as an TextTyped event on the document or application objects.</p>
  
  <p>Does anyone know if this is possible without polling the document?</p>
