Provide default value or press key to exit prompt

[banhmisg9509]

I have a problem when the user want to exit the file selector prompt. They don't know what button to press to exit when there aren't any valid file to select or the root folder was empty. So I think the prompt should provide a default value or callback when press key e.g ESC

I see same issue here SBoudrias/Inquirer.js#454, but not get merged.

As for me, this feature is better to be implemented in InquireJs but not a plugin to make consistent experience.
