With regards to this question, the solution provide to get
backspace for going back in nautilus does not function any longer. I would like to know if there is a functioning workaround for nautilus 3.18.4?
With "going back in nautilus" I me to go up the path, i. e. from
(gtk_accel_path "<Actions>/ShellActions/Back" "BackSpace")
(gtk_accel_path "<Actions>/ShellActions/Up" "BackSpace")
~/.config/nautilus/accels and a subsequent
killall nautilus does the trick.
As can be found in this and this thread, Nautilus (since 3.15.4) no longer uses
GAction. A fact not known to me. Is there a way know how to edit
GAction, without patching it as proposed here?
