The option of displaying "Not Selected" pages in Google Webmaster Tools seems to have retired. We're now only provided the options of total indexed, ever crawled, blocked by robots and removed.
I found the not selected option a pretty good diagnostic tool and an insight into what Google thought and I'm sad to see it go. It seemed buggy though.
