 ## Background
 
 As I said, this project is based in [tmux-fingers](https://github.com/Morantron/tmux-fingers). Morantron did an extraordinary job, building all necessary pieces in Bash to achieve the text picker behaviour. He only deserves my gratitude for all the time I have been using [tmux-fingers](https://github.com/Morantron/tmux-fingers).
