The Plugin you used in this example supports parameters like onComplete, onItemClick. hence refer to their documentation for more examples,
 
As a suggestion you can find "onItemClick" option as an alternative for onkeydown
 
Example Code Snippet:
$(".s1").dropdownchecklist( { forceMultiple: true
   , onComplete: function(selector) {
       var values = "";
       for( i=0; i < selector.options.length; i++ ) {
           if (selector.options[i].selected && (selector.options[i].value != "")) {
               if ( values != "" ) values += ";";
               values += selector.options[i].value;
           }
       }
       alert( values );
   }
   , onItemClick: function(checkbox, selector){
       var justChecked = checkbox.prop("checked");
       var checkCount = (justChecked) ? 1 : -1;
       for( i = 0; i < selector.options.length; i++ ){
           if ( selector.options[i].selected ) checkCount += 1;
       }
       if ( checkCount > 3 ) {
           alert( "Limit is 3" );
           throw "too many";
       }
   }
       });
