Comment-out code block

[mbakker7]

Anybody know how to comment-out a code block in JupyterLab 4?
It used to be: select code and use CTRL + /
Doesn't seem to work when running Jupyter Lab 4 on Safari. Is there another magical key-combination?

Greetings @mbakker7

Yes, there is another way to comment-out a code block in JupyterLab 4. Here's how you can do it:

1. Select the code block that you want to comment-out.
2. Press the Cmd key and the / key at the same time. This will comment-out the selected code block.

Alternatively, you can also use the following key combination:

1. Select the code block that you want to comment-out.
2. Press the Ctrl key and the Shift key and the C key at the same time. This will comment-out the selected code block.

These key combinations should work in JupyterLab 4 on Safari. Let me know if you have any other questions or concerns.

Cmd + / works like a charm. Thanks!
(But Ctrl + Shift + C does not work on my Mac. But that is a less convenient key combo for me anyway.)

In Windows 11, neither works.

1. Ctrl + / works occasionally, but more often it becomes ''' (3 apostrophes)
2. Ctrl + Shift + C: I see search box pops up, nothing to do with commenting.
   I have been frustrated by this problem (Ctrl + / not working) for 9 months now.
   In the meantime, there's no replacement within selection, which is also missing but very basic edit function.
