Typically when you want to choose an item from a list for an edit panel field, you click on the disclosure button to the right of the field. This allows you to choose the desired list item.
If you wish to see all list items containing the text in the field, you can use this menu item. Selecting an item in the displayed popup menu will set the field to the item's title. Note that leading words in the Natural Sort Exception Set are ignored. This ensures that if the list item does not have a leading article and the field does, the item will be matched.
This menu item is equivalent to a function button's menu item with the same title. It is primarily available on the application's menu bar so that a keyboard shortcut can be applied. The application menu item or an assigned keyboard shortcut will only work while you are editing an appropriate field.
