Backspace shortcut for explorer

Solution 1:

I don't know how to use Backspace, but there are a few Keyboard shortcuts:

Alt+Left - Move 'Back' through history of navigated folders

Alt+Right - Move 'Forward' through history of navigated folders

Alt+Up - Move 'Up' - navigate to parent directory

There are more listed here

You can change it to be the shortcut to navigate back, though it might be simpler to use Alt+Left.

First kill nautilus with:

nautilus -q

^{Note this will close any file manager windows, and probably anything it is doing}

Open the text editor with the file by running this in terminal or command prompt:

gedit ~/.config/nautilus/accels 

search for this line (Ctrl+F and then type actions/Up):

; (gtk_accel_path "<Actions>/ShellActions/Up" "<Alt>Up")

and replace it with: (gtk_accel_path "/ShellActions/Up" "BackSpace")

Save and exit, then close terminal, and open Files again, and it might work
