There are a few issues here.

- Remove all tabindex attributes from the page. They create a VERY
illogical navigation order - 1. search text box, 2. page name in the
breadcrumbs, 3. an empty element after the breadcrumbs, 4. the logo,
5. the "skip" link, 6. the remaining search controls, etc.

- If possible, restructure the code order to match the visual order.
In navigating and reading through the page, the order is quite
illogical - main content, breadcrumbs, main navigation, side
navigation, links at the very top of the page, footer.

- Remove the empty links from the page or provide text in them. The
cells in the "Ritröð" column all have links, but most of them don't
contain any text. There are 4 or 5 empty e-mail links in the footer.
Etc.

- To make the items in the "Aðgerðir" column keyboard navigable, they
should be placed within links. The role="button" attributes should be
removed - these are links, not buttons. Role="button" does not make an
element navigable or function as a button. The script events would
need to be moved to the anchor elements, not the images.
Alternatively, the images could be changed to <input type="image">,
but again, they aren't really buttons at all. Or the images could be
given tabindex="0" and scripted to respond to keyboard Enter and Space
commands.

Hopefully this helps.
