Hi, I think this topic is still actual. Don’t you plan to realize the things you suggested? I think this would help the learners to focus more on the coding itself, spending less time Googling for aspects of the game itself.
For now, I hope this info might help the users:
- Special shortcuts contributed by the game itself are here: https://github.com/codecombat/codecombat/blob/master/app/templates/play/level/modal/keyboard_shortcuts.jade#L7-L76 (as @nick wrote).
- General editor shortcuts contributed by the Ace editor that is probably used “underneath”: https://github.com/ajaxorg/ace/wiki/Default-Keyboard-Shortcuts (as found in How to comment multiple lines in the code).
