Undo text entry in Jupyter Notebook under Win7

I was surprised I did not find an answer to this question on Jupyter Notebook under Win7 here or on the web.

I just overwrote by mistake a larger part of a call block, but not all. Autosave dates back some previous changes that I do not want to revert. Where is the undo function for text entries in Jupyter Notebook?

Hit the ESC key to enter Command Mode. Now you can hit the h key to see all available commands. To undo an entry you have to go back to Edit Mode (hit ENTER) and then do a CTRL-Z.
