title: Event for blinking line moved in textbox
body: <p>I have been wondering how to fire an event for when I move the blinking line in a textbox.
  I would like this event to contain information for the current (Line, Column) position of the line.
  For example if I start out at 0,0 and press enter 3 times how can I get the new coordinates of the line?</p>
  
  <p>Sorry if I didn't explain this question as clearly as possible.</p>
  
  <p>Thanks.</p>
