(In reply to Henry Wilkes [:henry] from comment #9) > Regarding keyboard navigation: I think I will just use one-directional keyboard navigation. I'm leaning towards Up-Down since this is what we do for the 3pane attachment list and other richlistboxes. I don't think this area needs 2-dimensional keyboard navigation (which would normally be for `role=grid`, which would be more complicated). Hmmm. Is this not some custom element which we want to use in more spots? Perhaps if we get 2-dimensional keyboard navigation right in the custom element (once-only effort), we could benefit everywhere? Such navigation functionality should really be inbuilt. Being limited to navigation which differs from the actual direction I want to take might be a bit irritating for the multi-layouts (vs. single-column).

But yeah, if we'd limit to 1 dimension, it should probably be up-down.
