Shortcut to navigate to next submission does not work with French AZERTY keyboard

[Jujuhop]

Hi support,

I have the following issue in Jupyter Lab/formgrader:

The shortcut used to navigate to the same place in the next submission ("CTRL + ." in theory) does not work. It seems that this is common for AZERTY keyboards but not for QWERTY.
However the "previous submission" shortcut works ("CTRL + ," ; note that "CTRL + SHIFT + ," does the same thing).

Thanks for your work.
I include some details below

Operating system

Linux Ubuntu

nbgrader --version

0.9.1

jupyter lab --version

Jupyter Lab 4.1.4

Web browser

Firefox 126.0.1 64 bit

Expected behavior

When browsing submissions the shortcut "CTRL + ." moves to the next submission

Actual behavior

Nothing happens with that shortcut.
