Key value is used to structure information found under each section of a record pane.
A key value is composed of a key and a value:
It is a unique identifier/label that allows easy access to the value associated with it.
The value is the information associated with a key. It can be anything such as a number, text, a list…
Key value allows the database to store data as a collection of key/value pairs.
When users edit a pane, the key should become the text field label and the value, the text field input.
