[Enhancement] Lettings users use arrow keys to navigate the search results

[DorkOrc]

Being able to use one's keyboard arrow keys to go down and up the list of results of a search in the "All Generators" page would be very handy. Sure you can Tab and Shift+Tab to go up and down without a mouse, but the muscle memory just isn't there for me and most search engines allow for the arrow keys to be used, so it'd be a nice touch here too.
