How to copy code from Jupyter notebook

edit

How do I copy code from a Jupyter notebook to paste it here? I cannot figure out a way to do it.

In the old sage notebook format you can get a text version of your code input output by clicking a 'text' button that is to the right of the 'worksheet' button. I find that very convenient when posting questions here.

But since Sage seems to be moving to the Jupyter notebook format from the old notebook format, I figured I better get used to the Jupyter notebook.

I'm running Sage in Virtualbox in Windows.

Thank you.
