I used to have a script called Backspace levering from python-nautilus to move back from one folder to the previous one using the backspace instead of ALT + < .
With the new versions (which btw look amazing) this function is not enabled anymore.
Would you be kind enough to explain how I can change this? For me, backspace is so important but I cannot get used to ALT + < as the ALT is too far from < (lol).
