'undo' does not work once command is executed

Questions

Hi,

undo does not seem to work once I have executed a command. Is there a way out of this?

If I get your question right, you’re asking for some multiple undo facility in Mathematica.
If this is so please consider this: https://mathematica.stackexchange.com/questions/1953/implementing-efficient-multiple-undo

A dmitted it is not the peak of a solution, but a working workaround on an ever annoying theme inside Mathematica notebooks.

Considering the evaluation model in Mathematica this is really hard to implement to be efficient, so I do understand
the existence of this limited capability.

Cheers

Stefan

Dear Balachander Narasimhan,

your question was already extensively discussed at an existing thread:

To undo, or not to undo, that’s the question

Please read carefully through that discussion. If you still have a question - post it as a comment there. Thank you!
