You can filter objects on the properties available for each displayed column in the List View. This makes it easier to get an overview of all objects.
You filter the objects using the filter function in the column heading. You select the criteria in the filter drop-down list.
For example, you can filter on all objects that are set to '21' in the Value column in the List View.
The settings you make in the filter are not saved when you leave or close the list.
