It actually is a option. You use pins like you use pins in the "recents" option. When you open 2010 Excel and lets say you have opened a few blank templates and a couple of samples, then you close them and close Excel. You can then open Excel, go to the "recent" option and in that block you have a few saved "worksheets". To the right of each one you will see an icon of a push pin by each doc. If there is one that you use a lot, you can click the push pin and it will go from a "unstuck" push pin to a "stuck" push pin. It will also move that doc. to the top. There IS a way to "pin" a worksheet to the screen so that no matter what you do on that screen , the doc. that you "pinned" will remain on top of the screen that you are working in so you do not have to keep hunting for it and especially during the tutorial, you can work together with it without "pulling your hair out trying to keep up with it"!! Once I have found it again, I will post it up here for you. I am "PO'd" because I just went over it last night.
