In all file managers on windows and linux except nautilus the backspace key is used to navigate back to last location, but nautilus uses alt+ [arrow keys] for navigation. Which is unconventional and very uncofortable as you have to use two buttons for the same functionality you are used to get with single key (Backspace).
This problem can be solved easily by using nautilus-python or python-nautilus package on fedora and almost all other linux distributions, as after installing this package you can put python scripts in a specified folder to extend functionality of nautilus.

So I request you to add this package to bundle prividing nautilus file manager.
OR
tell me other workaround (if available).
