Screenreader / access / keyboard shortcut / alt text support

[angrave]

Up-down-buttons need keyboard shortcuts.
i.e. Should be able to navigate site using keyboard and without using a mouse/touch.
All images should have alt and title text.
What can we do about the graphics2G/simulation map? Set an alt text that describes the current actor and current flag position?

FYI
New versions of ace support an accessibility theme that works well with screen readers. Need to investigate and incorporate.
Do we need an accessible version of the map?

"I'm an intern at Google for the accessibility team who is working on making the Ace editor more accessible to blind users. Google has an open source extension called ChromeVox that is a screen reader for Chrome. I've created a theme for Ace that uses ChromeVox's API to read out loud code as the user navigates around, and I would like to contribute it back to the Ace codebase."
