One of the nicest additions FileMaker made awhile back was within an area you wouldn't quite expect. It was within the Summary functions that FileMaker added a simple new option named ListOf. This happened with FileMaker version 13 and this one type of summary field can be use for so many different things within the user interface that it's quite invaluable for driving all kinds of user feedback.

With a ListOf summary field, you can control the content of a custom portal, grab data necessary for looping over, or simply show the user an overview of the records they have loaded in the current found set.

Understanding how to use, and take advantage of, the ListOf summary field is what this video is about. We'll walk through two different uses and take a look at a nice user feature which allows the user to determine which data they would like to interact with. If you've never used a ListOf summary field, then you certainly need to be aware of what's covered within this video!
