Recommended keyboard shortcuts

[seeM]

Related to https://github.com/fastai/nbdev-vscode/issues/20, we could also add recommended keyboard shortcuts that aren't in Jupyter:

• cmd+shift+enter: Restart and rerun all cells
• q q | cmd+enter : Run all cells
• q a: Run cells above
• q b: Run cell and below

Are there any preferences for what these keyboard shortcuts should be? We can include multiple too.

I personally also like these VIM-like shortcuts when in command mode:

• g g: focus first cell
• shift+g: focus last cell
• ctrl+d: page up
• ctrl+u: page down
• h: folds selected section
• l: unfolds selected section

Unfortunately I don't think there's a command to jump to the previous/next section heading like with Jupyter's Collapsible Headings extension.

What do you think?
