ShourCut Plugin Problem

ShourCut Plugin Problem

Hello All
    
    I Am using a Shortcut Plagin with jQuery. To add a Shortcut i simply use
        
  1. shortcut.add("Ctrl+A",function(){ 
  2.     alert('A is Pressed') 
  3. });
    and to remove a shortcut
  1. shortcut.remove("Ctrl+A");
    but whenever i am using this code to remove a shortcut outside the jQuery Bode it gives an error oh "Object Expected" But inside the jQuery Body it works fine
