Up and down arrow key does nothing in search result.

[JunHuang01]

I've looked into this problem a little bit.

Up and down arrow key does nothing in search result keys are not working as one normally expect. And we are preventing anything from happening with

    this.inProgressSearch = _.debounce(function(ev) {
      ev.preventDefault();
      if (ev.keyCode === 13) { // Enter
        return;
      }

So basically I have a rough idea what needs to happen if we wants to enable hotkey on search result selection.

Let's talk about what exactly do we expect.

Do we expect that arrow key will move up and down in search results?

Do we expect when enter is hit, we would select the highlighted search result.

And in case the search query is not yet completely entered, but we do have a suggested search result, when enter is pressed at that point, that none other search result highlighted, and the search query is incomplete, we would show the suggested search result at that point?

And what I have in mind to get it to work is something like this:
