Shift+Tab and Tab work in the current editor as well. Or do you mean beautifiers or such? These are currently absent.
But what is worth, I'm already adding monaco editor to ct.js (: maybe will release a new version with it these weekends.
Thanks, I look forward to the next release. I started using ct.js two days ago, 10/09/2019, and I'm really enjoying it. I am also studying the code to help you with development of the ct.js.
