Is there a when expression detecting whether the cursor is at the beginning of a cell?

Thanks for the nice extension!

I want to custom the notebook.cell.quitEdit with keybinding left arrow when the cursor is at the beginning of a cell. Is there a when expression for this purpose or is it possible to add this functionality?

This is a good idea !
Also for keybinind up arrow, so you don't go through the lines, but rather through cells. Wish they provide a context

I would like this too. I don't see any existing expression that would work. I suspect it would have to be a feature request on the main repo however: https://github.com/microsoft/vscode.
