Better support for running code from other kernels/languages in interactive window?

[nickeubank]

I'd love to be able to use shift-enter to run R code in an interactive window, but I can't get the keyboard shortcut to work.

If I drop the jupyter.ownsSelection in the when condition, I can run the R code in an interactive window, but if I try to run code in the interactive window console, instead of running in the window, launches a new interactive window in some kind of recursive comedy routine...

Thanks for the suggestion. There was some attempt at this here for markdown:

#4876

It was intended to support other languages.
