That is correct, there is no high level undo that would work across different fields in a global fashion throughout the software. It would take quite an effort to make that possible, given nothing in the kit works that way. It’s not like a spreadsheet, which is a single document, it’s more like a database or a form—at least in terms of how the GUI operates. I don’t think there is anyone that would argue for it working the way it does, on purpose, but it’s one of those things that would take such an effort to accomplish, we could probably fix hundreds of other things in the meanwhile.
Was it new data, or something that has been around since before today? If so, you can probably recover it from a recent backup.[1]
Incidentally, the outliner is supposed to work way better than it does.
Refer to §5.2.3, Restoring from Backups if you haven’t done that before. ↩︎
