Goals
Provide spatial navigation support for game controllers, remote controls, and other limited input devices. It is currently difficult/annoying to navigate from link to link on a page using a device that doesn't have standard mouse or touch controls -- this feature will provide the ability for users to "tab through" links when using these devices.
Specifications
tbd - need specifics about which devices we're going to address initially (game consoles, tvs, etc...)
User stories
tbd - need specifics here around which controllers/buttons/devices
