This is the same output they get when they say '?'. However, the unknown command may be due to a user input error rather than the user not knowing the valid command. To reduce the likelihood of user confusion and error repetition, instead of displaying the list of accepted commands, display a short error message with the unknown command received, as feedback to the user. Include a reminder about the current command '?' in the new message, to guide the user if they want help.
