Arrows are out of functionality

[MohammadJavadSoltani]

I'm try to use arrows in kyboard (up-down-left-right) and there is no response! These work fine in the JUPYTER notebook environment.

thank you for your time.

Hi @MohammadJavadSoltani thank you for opening this issue! Can you share the versions of the Jupyter packages you are using (via jupyter --version) and the version of nbclassic you are using (jupyter nbclassic --version)? Also, could you share more of what you are trying to use the arrows for? Is it for the directory listings or within a notebook file?

Thank you for the follow-up information @MohammadJavadSoltani! Are you seeing this when you are editing the contents of a cell or when you are navigating through various cells?

[MohammadJavadSoltani]

unfortunately, in both subjects, arrows doesn't work!

@MohammadJavadSoltani Thank you for your response. Can you share info about what operating system and keyboard layout you're using? It could be that the arrow keys aren't sending the key codes that JupyterLab expects as arrow keys.

[MohammadJavadSoltani]

@JasonWeill Thanks for your time! Honestly, I changed my workspace to VS, but I really like Jupyternotebook, so I would love to resolve the problem. I tried again; it looks like the problem is in Ceels; arrows aren't properly working there, but I can change cells and go up and down outside of cells.

I'm working with the Lenovo Legion Y520. It's strange that in Jupyter notebook everything is fine!

I really like Jupyterm

Do you mean that the issue happens in https://github.com/davidbrochart/jpterm or https://github.com/vinayak-mehta/jupyterm ? Or does it happen in Jupyter NBclassic which is basically Jupyter Notebook v6 but using jupyter-server?

[MohammadJavadSoltani]

so sorry about the confusion; it was an spelling issue, i definitely use NBclassic.
