Recovering previous saves.
In the old days of FCP7 I used to use the "save as" function all the time to save versions of a project for safety reasons e.g. A1,A2,A3 etc so I could go back to a previous, earlier version in an emergency or crash. I just edited a project on FCPx and for whatever reason it disappeared, a completely empty time line, gone for good,kaput. Am I correct in thinking that you cannot recover a previous version autosaved at an earlier time? Do you by definition lose the whole project and have to start again? Luckily in this case it wasn't important.
My second more trivial question is whether there is a command to push forward or backwards on the time line a whole clip?At the moment I am using the Position tool but its a bit clumsy doing it this way.
