Undo cell deletion in Google Colab

I am trying to use a shortcut to undo cell deletion in Google Colab. When I delete a cell, Google Colab displays a hint that I can undo the action by using Ctrl + M Z

Is this shortcut means clicking Ctrl + M + Z all at the same time? Because it is not working for me.

It means "first press Ctrl+M, release, then press Z" - surely this is a bit confusing!
