title: Excel 2010 CTRL+SHIFT+L. Not working
body: <p>I apologize if asked/answered - but I truly did search....</p>
  
  <p>In excel CTRL+Shift+L is not working;  when I press the key sequence and the cursor spins and comes back without having accomplished turning on the filters or anything visible to me.  This is the only shortcut that is not working so I did not know if I redefined it - but could not tell what it was currently defined as,  I had the IT guys repair the install - All with no luck...</p>
  
  <p>I would love to debug what CTRL+Shift+L does when I hit it - but could not figure out if that was possible...</p>
  
  <p>Totally at wits end - - any help would be greatly appreciated.</p>
