If there's a corresponding line starting with `$` for a variable, suggestions will be displayed. Otherwise, the user will be able to type any value for it.
If you hit `<tab>` the query typed will be prefered. If you hit `<enter>` the selection will be prefered.
### Advanced variable options
For lines starting with `$` you can add use `---` to customize the behavior of `fzf` or how the value is going to be used:

```
The supported parameters are:
- `--allow-extra` *(experimental)*: handles `fzf` option `--print-query`. `enter` will prefer a selection and `tab` will prefer the query typed.
- `--multi` : forwarded option to `fzf`.
- `--header-lines` : forwarded option to `fzf`
- `--column` : forwarded option to `fzf`.
- `--prevent-extra` *(experimental)*: limits the user to select one of the suggestions;
- `--multi` : forwarded option to `fzf`;
- `--header-lines` : forwarded option to `fzf`;
- `--column` : forwarded option to `fzf`;
- `--delimiter` : forwarded option to `fzf`.
