Google's Supplemental Index?

I don't want my pages in the supplemental index. I want to be in the main index.
- What pages are in the supplemental index? I need to figure out how to know. I might find out that it's my hint pages which are almost all flash or some other page of that sort.
- I need to study these pages and see if they are repetitive or whats going on
- Maybe I should take them out of the google index entirely with robots .txt file....

Thanks to Mapelli for this tool and info.
I found this info by following links from the great article on free seo tools.

Here are two good, but old articles, on breaking out of supplemental. Matt McGee's and SEO Book. The latter had some info to see what results are in the supplemental index.

If you want to view ONLY your supplemental results you can use this command site:www.time4learning.com *** -sljktf. I don't think this worked for me.

I'll now (or when I get back to it) try looking at the data and difference between:
http://www.google.com/search?q=site%3Adomain+-inallurl%3Adomain&filter=0 http://www.google.com/search?q=site%3Adomain&filter=0
