Any way to revert back to before a mistaken save?

The program is Numbers. I don't have Time Machine configured - I think I'm up a creek, but I figured I'd check here just in case.

You nailed it. It's called a backup.

Yup. Setup time machine man. You could recover from the previous hour backup.

Do you use DropBox? DropBox automatically versions each save.

Consider purchasing Foreversave. For $15 it is money well spent and it also functions as an autosave which iWork Apps don't have. You can configure it to keep whatever number of previous versions that you like.

That doesn't help for now, but it prevents this from occurring in the future.

Foreversave works for me

I use it on Office for Mac, as both Word and Powerpoint sometimes crash so badly that the autorecover fails to save anything; and for Freeway Pro, which has no undo option

I set it to back up EVERY MINUTE in Freeway Pro, so I can always backtrack when I can't undo.

The config documentation is a bit confusing, but once you get it working, it increases your confidence significantly
