Do you want a PDF Help Manual?
I find the online help cumbersome. If you do as well here is how to make a PDF of it.
1. Go here http://help.apple.com/finalcutpro/mac/10.0/
2. Click on the printer icon in the top right corner and select "Book".
3. In the printer window click the "PDF" button and select "Save as PDF".
