## External configuration
In order to improve the `fzf` preview window display, it's possible to
configure it through the following `env` variable:
```bash
export FZF_DEFAULT_OPTS="--preview='bat --style=numbers --color=always --line-range :500 {}' \
--border \
--color 'border:#4c566a,info:#4c566a,pointer:#88c0d0,prompt:#5e81ac,bg+:#3b4252,hl:#a3be8c'"
```
