Saved and Key fields have been replaced by Searchable Fields.
Key and Saved fields have been simplified into a single concept for Submissions View 2.0. The single concept is named Searchable Fields and technically is a rename and extension of the old Key Fields functionality. The searchable fields configured for a form or flow are the fields that may be use to filter submissions in the submissions view.
The screen below illustrates the edit mode administration dialog that is available when the user clicks the "setup Searchable Fields" link in the form or flow editor. The "setup Searchable Fields" link replaces the old "setup Key/Saved? Fields" link.
The administration of searchable fields is very similar to the legacy administration of saved fields. It supports drag and drop and left and right buttons similarly to the saved fields ui in order to added searchable fields.
There is a configured max number of searchable fields supported (see section 3.4). When an attempt is made to add a searchable field in excess of the maximum configured number of searchable fields, the user will see an error message ("Maximum Number of Searchable Fields Exceeded!"). The message will appear on the lower right of the screen illustrated below and will disappear after a short time. Any fields in excess of the max configured will not be allowed.
