Keyboard focus gets stuck at code text-area

Goal: I want to submit my exercise answers w/o using a mouse.

Issue: I am unable to Esc or Tab out of the code text-area to the "Run" button to submit my code answers. It might seem that the focus is stuck in the code text-area... but I have the ability to "Tab-Shift" back out in the opposite direction. Is there a keyboard shortcut to submit my exercise answers?

Proposed Solution: Not sure exactly how atm, but, to enable keyboard only navigation and usage of 4ever-clojure. Accessibility fixes and/or keyboard shortcuts could be possible resolution routes.

Would it be helpful for me to investigate potential fixes?

Thank you guys for making 4Clojure continue on!

Ps. I also noticed that the successful exercise submission modal does not trap user focus as it should - this will make the site less accessible for differently abled visitors. There are a few ways to fix this that keep dev work to a minimum while offering maximal accessibility - I'm happy to support as I can!

Start by reproducing keyboard navigation in the exercise code text-area and the successful-submission modal. Done means keyboard-only users can reach the Run button without a mouse and focus is handled appropriately when the modal opens.
