This is only possible because the working memory of the 31S is way below the 2K RAM we have available. Implementing such a feature is just impossible on the 34S.

The undo save could be in the non-battery-backed 4K of RAM. If you turn the 34S off, or leave it idle so it turns itself off, then undo would not be available when you turn it back on.

Of course, there might not be enough Flash space left to implment that. I don't think there are many features that I'd be happy to dump in favor of adding undo.
