How to recover deleted Jupyter notebook cell?

Question

I use Jupyter notebook. I accidentally deleted a cell, and I can\'t go step back.

How can I recover the notebook cell?

Answer 1

If you need to undo something deleted inside a cell, press:
CTRL/CMD + Z

If you need to recover an entire deleted cell hit:
ESC + Z.
Especially this second tip might be useful if you delete a lot of cells by mistake.
