Alt key behaviour with Javascript on Chrome/Windows 7?

I'm trying to emulate a behaviour of a windows menu where you could navigate menus using an combination like: alt + KEY + KEY ... as a simple test I did this:

$(document).on('keydown', function(e) {
  $(".dropdown>a").css("text-decoration","underline");
}).on('keyup', function(e) {
        $(".dropdown>a").css("text-decoration","")
});

Which should add or remove an underline for all my links under .dropdown whenever I press any key on the website, it works fine for all , but the Alt key, with this key the system appears to be awaiting another key to be pressed and will only show the underline if I press alt twice.

I'm wondering if this is something that can be worked around or is something regarding the operating system. Why does is happen?

It can be related to how your browser handles the alt key, might be it activates its own menus. Your code works fine for all keys including alt on my ubuntu+chrome.

You can also check if e.preventDefault() solves your problem.
