The only solution I can imagine would require keeping a practically limitless memory of every step the user did to get to that point. Unless you're talking about a simple one-level "undo" though, which we already have. What I had in mind was this: 3.14 --> '3.14' Just adding the quotes! Wasn't thinking of undoing operations to get the original expression that led to the number (that would be cool, but like you said we'd need a more powerful device, perhaps a phone/tablet to keep the history). Within the limitation we have, at most something like QPI could be implemented. |
