Check Ctrl / Shift / Alt keys on ‘click’ event

Well you this wont work in all browsers just IE 8. Microsoft implemented the ability to determine which (right/left) key was pressed. Here is a link http://msdn.microsoft.com/en-us/library/ms534630(VS.85).aspx

I also found this wonder article about keypress, keyup, keydown event in browsers.

$('#someelement').bind('click', function(event){ 

    if(event.ctrlKey) {
      if (event.ctrlLeft) {
        console.log('ctrl-left'); 
      }
      else {
        console.log('ctrl-right');
      }
    }
    if(event.altKey) {
      if (event.altLeft) {
        console.log('alt-left'); 
      }
      else {
        console.log('alt-right');
      }
    }
    if(event.shiftKey) {
      if (event.shiftLeft) {
        console.log('shift-left'); 
      }
      else
      {
        console.log('shift-right');
      }
    }
  });
