title: Zend Studio 7 code folding
body: <p>just another simple question (as always). 
  I have tried to find out how to fold a PHP function using shortcut in Zend Studio 7 and have found on the Preferences section that the shortcut is Ctrl+Numpad_Add.</p>
  
  <p>I tried it and also changed into new binding key, but it is still not working.
  Any idea how to do it?</p>
  
  <p>Thank you.</p>
