No, inserting text is a command (it's the self-insert-command). Presumably how it would have to be done is when some software (like Emacs) launches it'd prompt the user for every required keybinding.
That concept breaks down with the multiple thousands of default key bindings in a typical Emacs setup (source: go into an org buffer press C-h b, then go to a Python buffer and press it again, and so on)
