I created versions of the different options we are discussing (to try, access beta wiki http://en.wikipedia.beta.wmflabs.org/wiki/Lightbox_demo with the test users indicated below):
- A: Panel opens with both up and down arrows (user: mv-both, password: 123) - B: Up and down keys act as default for scroll (user: mv-none, password: 123) - C: Provide image and data on a continuous page (user: mv-page, password: 123)
I'm ok with A or B. I think A provides a better solution to the user intent (view the metadata), while avoiding diverging from the standard scrolling direction too much. If A still generates confusion, I'm ok to default to the browser defaults, but I think the line-by-line increment will led most people to unnecessary additional key presses.
I think that changing completely the metaphor we are using (as in C), will bring more problems than benefits (e.g., what to do with the controls over the image).
I'll do some quick tests with some users, but feel free to provide your impressions when trying the above.

I think that picking isolated websites (gmail or medium) isn't enough to get a sense of what the average user's expectation is. These two particular examples aren't necessarily the best for other reasons: Google products and Gmail in particular have always had very engineer-minded keyboard shortcuts because engineers rule the culture at Google. That's not necessarily the best thing for accessibility if you don't have that culture. As for Medium, it's too new to have proven itself as something with good accessibility. Maybe a lot of people are getting confused by medium's interface, we wouldn't know.
Possibly, it would help to re-word the way we're understanding these 2 examples, into the abstracts that they represent:-
In line- or list-item-highlights, like email programs (Thunderbird, etc), or file managers, or spreadsheets, or drop-down menus:
- Clicking the keyboard down-arrow will move the highlight downwards by
exactly one (1).
In full-window-highlights, like a PDF-viewer, or image-viewer, or webpage:
- Clicking the keyboard down-arrow will make the content scroll-upwards.
(by a variable amount, depending on OS, program, and user-settings. Sometimes 1 line, sometimes 3 lines, sometimes x pixels.)
(and similar results for left/right arrow-keys)
