# add a command using your favourite editor to easily edit your config
> elfs -cc "config" "" "" nano ~/.config/elfs/config.json
# or add a command to easily edit your spellbook (you can move this file)
> elfs -cc "spells" "" "" nano ~/.config/elfs/spellbook.json

Unless using search (and select), the default behaviour is to find a command using exact matches only, and are selected in the following order of precedence

1. files in order of directory listed in config
2. names of commands from spellbook in order listed
3. imply file extension if unambiguous
