 |$tags |An optional subfilter expression, which takes the <<.field tags>> field of the target tiddler as input, and saves the modified list of tags back to the <<.field tags>> field |
 
+!! Note on subfilter expressions
+
+If the manipulation depends on the current contents of the list, e.g. when using the <<.olink toggle>> operator to toggle the presence of an element, the [[Filter Run]] would be prefixed with the `+` / `:and` [[filter run prefix|Filter Expression]] so that it properly receives the list as input. 
+
+```
+<$action-listops $subfilter="+[toggle[List Item]]"/>
+```
+
+The above widget will toggle the presence of the element <<.value "List Item">> in the field <<.field list>> of the current tiddler, removing or adding the element as necessary.
+
+Similarly, if an element is to always be removed when it is present, the `-` / `:except` [[filter run prefix|Filter Expression]] can be used. Both of the following yield the same result:
+
+```
+<$action-listops $subfilter="-[[List Item]]"/>
+<$action-listops $subfilter="+[remove[List Item]]"/>
+```
+
+Without any prefixes, the filter run output is simply [[dominantly appended|Dominant Append]] to the list.
+
+See also the [[Examples|ActionListopsWidget (Examples)]].

 Standalone use of the `$subfilter` attribute can be replaced by using a (more complicated) `$filter` attribute value.
