title: Moving a DIV repeatedly by clicking and holding down the mouse button
body: <p>I'd like move a DIV 1px each time I click an arrow icon.  No problem there.  But now I'd like to have the DIV continue to move left 1px every 100ms when I click the arrow icon and <em>hold</em> the mouse button down. Is there a standard way in jQuery to do this?</p>
  
  <p>Thanks</p>
