Not sure whether this qualifies as a bug or not, so I'm putting it under feature request. If you use the tab key to navigate, an extra link appears at the top: Skip to Content. If you press tab again, you get the link Skip to Navigation. Press tab a third time, and you go to the first link in the page.
Skip to Content is clearly useful, allowing you to skip headers and sidebars and go straight to the content area. But Skip to Navigation apparently takes you to the same place that you'll end up in anyway: the first link in the page. So why have it?
I would like to see Skip to Navigation replaced by two links: Skip to First Sidebar and Skip to Second Sidebar, so that keyboard navigation users can go straight to the blocks in the sidebar if they want to. I think those would be vastly more useful than Skip to Navigation. Thanks!
