Additional context

I have to admit I never used the tab key, there are a lot of keyboard shortcuts to navigate between entries. I can reproduce the issue but I don't know why it happens. It stops if I make either the header or the star and open link icons unfocusable (tabindex=-1), but I don't know if this is acceptable. May I ask how you use the tab key to navigate CommaFeed?

I was also puzzled as to why this happens! I thought it was better to write it down anyway.

As for how I'm using CommaFeed: I like to go through a feed by marking each item as 'read' in sequence. I usually do this with the mouse, but I would prefer to do it with the keyboard. I know that the universal way to move between focusable elements in sequence on webpages is using the TAB key, so that's what I tried. Hope that's helpful
