Description

notebook-commands under-discussion

Does this issue occur when all extensions are disabled?: No (python + jupyter notebook enabled)

  • VS Code Version: 1.124.2 (user setup)
  • OS Version: Windows_NT x64 10.0.19045

Steps to Reproduce:

  1. Open a Jupyter notebook that has at least one Markdown heading followed by code cells (so a foldable "section" exists).
  2. Open Keyboard Shortcuts (Ctrl+K Ctrl+S), search for notebook.section.runCells, and assign any key combination (e.g. Ctrl+Alt+R).
  3. Click into a code cell that belongs to a section.
  4. Press the assigned shortcut.
Expected

The cells in the section containing the active cell are executed — the same behavior as clicking the "Run Cells In Section" triangle in the Outline.

Actual

Nothing happens. The command silently does nothing.

Cause

notebook.section.runCells reads its target cell/notebook exclusively from the menu context argument (outline entry or cell context). When invoked via a keybinding or the Command Palette, no such context is passed, so the handler returns early without doing anything.
