### 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
