Screenshot could include key

[russcd]

I would love it if the screengrab feature could also export the key in the lower left as it displays when exploring (as in the pango key in the screengrab below). This would be super helpful for creating images for talks/demos/etc.

Thanks!

👍 this clearly makes sense. unfortunately these are very different from each other (the key is HTML, everything else is not) so this is pretty hard and likely won't be imminent
