Prerequisites

• Install the Jupyter and Python extensions
• Have python installed, or a jupyter server available to connect to
  • the Jupyter extension should help with installing any required python packages

Testing

1. Set keyboard shortcuts for interactive.input.focus and interactive.history.focus
2. Create a python file with some # %% cells with some code
3. Execute cells in the Interactive window through a mix of code lenses, run in Interactive window commands and the input box.
4. Use the interactive.input.focus and interactive.history.focus commands to navigate to the IW
   1. You can give focus to the most recent IW input from anywhere, but history will only get focus when already in the input box
   2. You can delete cells (and undo), and re-execute cells in place

Try with different settings for jupyter.interactiveWindowMode and multiple windows
