Add the ability to turn OFF arrow key navigation in album layouts.

In Firefox 14, W7, when I press one of my arrow keys in an album layout, I'm taken to the next image. This isn't a browser bug (such as caret browsing being turned on) because the page actually "animates" down to the next image.

On a standard 1366x768 laptop, this means I cannot read any of the image captions and is incredibly frustrating.

Pressing the up or down keys results in the entire page going to the top or bottom, as if I'd pressed Home or End, respectively.

Strangely I do not get this behaviour using Chrome.

Please add the ability to disable arrow key navigation entirely as I prefer to have the default controls in my browser back.
