It would seem to me that this approach assumes the user is wrong to
press "down", and needs re-education.  Mark is making the case that
we're fighting expectations set by pretty much the rest of the web,
and that we may need to make more of a change than providing a more
prominent hint.  My personal experience concurs with this.  The Snow
Fall example[1] (and many others like it) show how
fixed-image-position scrolling like we do is compatible with the
traditional expectation of up-arrow/down-arrow behavior.

Of course, I'm going to allow for the possibility that I'm cranky and
old school, and that I just need to learn to hit the correct arrow
key.  :-)

Which is more intuitive depends on your mental model. If you think of the metadata panel as something that opens and closes, pressing up to bring it up and pressing down to bring it down makes a lot of sense. If you think of it as part of the page, that is currently out of view, it's the opposite. The current layout of MediaViewer reinforces the first model, IMO, with the image not scrolling when the metadata panel moves.

Either way, it's important to support both models. We currently do that by flashing the panel controls if you press the wrong direction - I think that's a good approach but the implementation is basically unnoticeable and should be made much more prominent. 

I have to agree with Mark here - it took me a while to discover the
up-arrow behavior, and I suspect users miss the metadata panel because
of this reversal of default direction.

I understand that it doesn't exactly behave as an incremental scroll
right now, but it's still confusing.

So.

When I go to a web page, and I'm browsing it, and I want to read *more
content*, I accomplish this in one of four ways:

* Scroll down with my scroll wheel or trackpad
* Scroll down with page down
* Scroll down with the spacebar
* Scroll down with the down arrow key

All of these work in Media Viewer, except for the last. You have to use
the *up* arrow key to accomplish a scroll-down movement. This makes NO
SENSE.

+1 from me.

Someone on the talk page has complained about this same thing [0] and
frankly that's enough reason for me to make more noise about it again.

Can we *please* rejoin the entire rest of the web in not screwing with
native browser scrolling controls, and letting people just scroll normally?
Do people actually like the up-arrow control for expanding the metadata
panel? Other comments about scrolling?
