Just installed Jupyter and I can escape out of cells into command mode and use the regular shortcuts just fine in Jupyter Lab. However, in Jupyter notebook, the commands are not accepted. For example, escaping out of a cell and hitting ctrl+a selects all of the browser text and not the cells.

I get exactly the same behaviour in Firefox and Chrome, so it doesn’t seem to be a browser specific or OS level intercept of the keystrokes. Similarly, it seems strange that it works fine in Lab and not Notebook.

FWIW I’m running Fedora 40 with GNOME 46

jupyter --version

Anyone understand what happening here? There seems to be another individual with the same issue based on this answer from a few years ago.
