@Garath: I have tweaked your posted code in order to make it work with results that are loaded via ajax. Thank you for bringing this up here.

    $(document).on("keypress",".select2-input",function(event){
    if (event.ctrlKey || event.metaKey) {
        var id =$(this).parents("div[class*='select2-container']").attr("id").replace("s2id_","");
        var element =$("#"+id);
        if (event.which == 97){
            var selected = [];
            $('.select2-drop-active').find("ul.select2-results li").each(function(i,e){
                selected.push($(e).data("select2-data"));
            });
            element.select2("data", selected);
        } else if (event.which == 100){
            element.select2("data", []);
        }
    }
});
