Google Reader knows when you made a mistake

Google Reader knowing what you did not mean to do. 

Back in the day if you accidentally pressed Shift+A in google reader you would find that you had just marked all your items as read. For some people this may not be a problem. For me, it is. I often have 1000 or more unread items, some of which I am deliberately saving so I do not have to keep track of them.

So, just a few moments ago I accidentally pressed Shift+A when going for Shift+S and I got the popup pictured above. Yay for Google's UI team.
