                else:
                    self.fm.select_file(fzf_file)

### hotkey mapping
    vim ~/.config/ranger/rc.conf
    


    map <C-f> fzf_select
    map <C-g> fzf_locate

### to include /media to the locate command database

    sudo vim /etc/updatedb.conf
    
    >>> remove /media from PRUNEPATHS
    >>> save and exit
    

    # refresh database
    sudo updatedb

### extra info

    From the Ranger man page :
    
    map key command
    Assign the key combination to the given command. Whenever you type
    the key/keys, the command will be executed. Additionally, if you use
    a quantifier when typing the key, like 5j, it will be passed to the
    command as the attribute "self.quantifier".
    
    In our case the quantifier is any key before pressing the fzf_select keybinding
