Right now if I do an alt-click (or ctrl-d) in the notebook extension it behaves just like the regular editor within a single cell. However, my workflow often involves using multi-select throughout a notebook because I have the same variable/whatever repeated in multiple cells near each other, but not in the same cell. It would be extremely useful if there was a way to make multi-cursor selections span multiple cells.

In fact, my work flow right now is to open a notebook in text only mode and use multi-select there with the jupyterlab interface open in a browser window. With this feature implemented I could dispense with the headaches of saving and reloading there and have it all in one vscode interface.
