Solution that should work for any keyboard layout:

Following this blogpost: https://towardsdatascience.com/jupyter-notebook-extensions-517fa69d2231, you can install some plugins for jupyter notebook with the command:

pip install jupyter_contrib_nbextensions && jupyter contrib nbextension install 

Now launch jupyter and go the new Nbextensions tab. There is a plugin called Comment/Uncomment Hotkey. Activate it and choose your hotkey. For example Alt + C. Now you can comment/uncomment a line or a block by selecting it and using your new hotkey.
