Why aren’t arrow keys working in my VS Code Jupyter Notebook using the Jupyter extension’s v2023.3?

This suggestion from https://github.com/microsoft/vscode-jupyter/issues/13263 solved it ror me, just add the following to the keyboard shortcuts json:

    { "key": "down", "command": "-editor.action.scrollDownHover", "when": "editorHoverFocused" },
    { "key": "left", "command": "-editor.action.scrollLeftHover", "when": "editorHoverFocused" },
    { "key": "right", "command": "-editor.action.scrollRightHover", "when": "editorHoverFocused" },
    { "key": "up", "command": "-editor.action.scrollUpHover", "when": "editorHoverFocused" },
    { "key": "home", "command": "-editor.action.goToTopHover", "when": "editorHoverFocused" },
    { "key": "end", "command": "-editor.action.goToBottomHover", "when": "editorHoverFocused" },
