Similarly, if an element is to always be removed when it is present, the `-` / `:except` [[filter run prefix|Filter Expression]] can be used. Both of the following yield the same result:

```
<$action-listops $subfilter="-[[List Item]]"/>
<$action-listops $subfilter="+[remove[List Item]]"/>
<$action-listops $subfilter="-[[ListItem]]"/>
<$action-listops $subfilter="+[remove[ListItem]]"/>
```

<<.infoBox """Note that the parameter of the [[remove Operator]] is a [[Title List]]. To remove one or more titles containing spaces the individual titles must be wrapped in double square brackets, usually via a soft [[Filter Parameter]]. See //Filtered List Variable Assignment// in the [[SetWidget]] documentation to learn more.""">>

Without any prefixes, the filter run output is simply [[dominantly appended|Dominant Append]] to the list.
