Since you didn’t really explain what you’re having trouble with, I just created a general solution. Hopefully this helps: var li = $(‘li’); var liSelected; $(window).keydown(function(e) { if(e.which === 40) { if(liSelected) { liSelected.removeClass(‘selected’); next = liSelected.next(); if(next.length > 0) { liSelected = next.addClass(‘selected’); } else { liSelected = li.eq(0).addClass(‘selected’); } } else { liSelected … Read more
