Not being well-versed in such matters, I'd appreciate any insight you can offer into why the Nav hijacking happens and what I might do about it.

I created the article using a WP plugin (Aesop Story Builder) which integrates with the WP theme I'm using (Journalist from UpThemes).

Oh. I looked into it a bit, looks like that's something "Aesop Story Builder" does. Not sure if they have settings that you can control through their interface. If they do, it looks like the relevant option might be called "arrowKeys".
