 | `@extrakto_fzf_unset_default_opts`    | `true`          | Unsets custom FZF_DEFAULT_OPTS as it can potentially cause problems in extrakto operations |
 | `@extrakto_open_tool`                 | `auto`          | Set this to path of your own tool or `auto` to use your platforms *open* implementation. |
 | `@extrakto_popup_position`            | `C`             | Set position of the tmux popup window. Possible values are in the `display-popup` entry in `man tmux`. Set this to `x,y` to set the x and y positions to `x` and `y` respectively. |
