When you have multiple elements from multiple categories selected in your model, an even quicker way to filter your selection is to select the pull-down menu just below the Type Selector. This will show the categories that have been selected and you can pick the category to filter.
This filter should be primarily used for smaller selections in your model.
It doesn’t work like the traditional filter, but it allows you to filter to a Category and alter the Parameters only. If you try to move or copy it will alter everything initially selected.
Another limitation to this filter selection, is that you can only select one category to filter.
