I have a two hour project all finished, and now I wish to make a twenty minute summary from it. What is the correct procedure to follow so that I do not lose my two hour version, but then I can also edit a copy.

Right-click the project in the browser and select "Duplicate as Snapshot". This will create a copy without dependencies to the first project. You can freely edit each one without affecting the other. This command is analogous to "save a copy as" in other types of applications.
