Tech - Google Reader, 1 problem sorted

Marking all posts as read (see yesterday) is extremely easy, it turns out. Simply press Shift-a.

Make sure you're in Only List Updated view.
Press g + a. That gets you to view all the new stuff in a list.

I view everything in List view.

Navigate your way round the list using the n and p keys. Use o to open up the full item, and press o again to close the item back down (and keep your place in the list view).

Finally, to mark everything as read, press Shift-a.

From what I can tell, navigating this way means that when I look at Google Trends (which tells me what I'm reading and what percentage of it I'm paying attention to), I'll get some meaningful information.
