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
