Code formatting without keyboard shortcut

[jeromebaum]

Livebook is a great resource for coding in Elixir. I've recently experimented with using it on iPad, using port forwarding via one of the many SSH clients available on iOS/iPadOS. It's working pretty well.

I've noticed is that it does not appear to be possible to format code without a physical keyboard attached. The on-screen keyboard does not have an option key, and there does not appear to be any button in the web interface to trigger the formatter. I was wondering whether it would be easy or difficult to add a format button to the code editor. That way it could be triggered without the keyboard shortcut. It would also advertise the format feature a bit. :)
