This is not well documented (or at all) but codemirror will only recognize <Esc> as the escape key. So if you capitalize the e then it should work

@ianhi Thanks all your efforts! I would like to send Cmd+/ in this box (to toggle comment), how do I achieve this? I tried <S-/> but it is not working.

It works very well with <Esc>
