Shortcut to comment out multiple lines in Jupyter Ipython notebook on Mac with French keyboard layout (without numpad)?

Question

I'm trying to select and comment # multiple lines using Jupyter Notebook on Mac with French keyboard layout and no numpad.

To type the slash (/) on this keyboard, the shortcut is Shift + :

When trying to comment lines on Jupyter:

• with Ctrl + Shift + : it doesn't work
• Neither Ctrl + #
• Or Cmd + :
• or Cmd + Shift + :

However on a Chromebook with French keyboard layout I'm able to do Cmd (search key) + : and it works fine.

I'm aware of this question: How do I comment out multiple lines in Jupyter Ipython notebook? but wondering if a keyboard shortcut solution has been found for Mac with French keyboard layout and no numpad?

Answer 1

@Jean: the jupyter notebook shortcut may be overwritten by the Mac View menu shortcut for Hide bar.

Answer 2

In my case, Ctrl+ § worked (with Switzerland keyboard no numeric keypad)
