Copying notebook HTML output not working for some keyboard shortcuts.

[regob]

Copying HTML output in ipynb notebooks does not work for keyboard shortcuts with Alt modifier key. The default Ctrl+c shortcut works, similarly, any shortcut with just the Ctrl modifier, e.g. Ctrl+9, but not Alt+9.

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.100.2
• OS Version: Windows_NT x64 10.0.22631

The issue is not present in version 1.99.3 (see detailed version info).

Steps to Reproduce:

1. Add a keyboard shortcut for copying that has the Alt modifier key in keybindings.json:

[
    {
        "key": "alt+w",
        "command": "editor.action.clipboardCopyAction"
    }
]

2. Open a Jupyter notebook with rendered HTML output. An example can be produced with any of these snippets (but can be reproduced without having the extensions for running python code installed):

import pandas as pd

pd.DataFrame({'x': [1, 2, 31]})

from IPython.display import HTML, display
display(HTML('<b>afsdf</b>'))

3. Select The HTML output and execute the copy shortcut. Ctrl+C copies the output, Alt+W or other Alt-modified shortcuts don't work.

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.100.2. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

I also reproduced in 1.100.2, and updated the info.

Hi thank you for filing this issue. While testing I see the following:

Screen.Recording.2025-06-11.at.17.25.37.mov

I am able to use the alt+w shortcut to copy output in notebooks when I explicitly select the output. When I just focus the output cell I am generally not able to copy even with cmd+c. Can you please include a screen recording of the issue as well as the settings file you are using?

Hi @aiday-mar!

The issue comes up when selecting the text in the output. I attached the recording, which shows it working with Ctrl+c but not with Alt+w and Alt+9. But only for HTML output, normal text output works.
