Setting keys opens the list. Add key appends a row. Save writes the list into the Graph draft (autosave).
At most 64 keys.
A Cron Enabled setting key, Code Settings keys, and
{{settings:…}} in a field must use a key from this list. Unknown keys show as a workflow issue.
Insert value
On a Graph field, Insert value includes Setting keys. Each row inserts a token like:settings: is the full key, including dots. It is not a path into a JSON object.
Previous nodes still lists connected node fields. Secrets stay on the same menu when the field allows them.
