Bring back `BackSpace` Keyboard Shortcuts on nautilus and thunar

Solution 1:

For Firefox and Nautilus: You can use Alt+← to go back instead of Backspace.

For nautilus 3.6 to bring backspace functionality you need to add this:

 (gtk_accel_path "<Actions>/ShellActions/Up" "BackSpace")

under

~/.config/nautilus/accels

And then restart nautilus by

nautilus -q or killall nautilus

In Thunar you have to add

(gtk_accel_path "<Actions>/ThunarWindow/open-parent" "BackSpace")

to

~/.config/Thunar/accels.scm

Solution 2:

For Firefox

Open firefox, type in about:config in address bar, press enter

Search backspace, should return 1 entry, browser.backspace_action

Right click on the value > modify & change from 2 to 0
