    Variant # 1 - use the MouseEvent.altKey property, which determines whether or not the alt key is pressed and returns true or false respectively:

     $(document).on('mousedown', function(e) { if (e.altKey) { console.log('alt+mouse'); } else { console.log('mouse'); } }); 
     <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

    Option # 2 - use a boolean flag to determine if the alt key is pressed:

     var altPress = false; $(document).on('keydown', function(e) { if (e.keyCode == 18) { altPress = true; } }).on('keyup', function(e) { if (e.keyCode == 18) { altPress = false; } }); $(document).on('mousedown', function() { if (altPress) { console.log('alt+mouse'); } else { console.log('mouse'); } });
