Yes, I've been meaning to implement that for a while now but I kept being indecisive about which keys should do what. Esc is a great option so I'll add at least that one for now. I'll send out an update in a day or so :)
edit: never mind, I really shouldn't have waited so long because hotkeys can be rebound quite easily so it doesn't actually matter so much what I choose as defaults. I've added a toggle on/off hotkey, and also 'esc' or 'e' will exit the cutscene. 'e' may be linked to open-inventory instead in the future
