The Key Text field allows content writers to enter a single string.
This field will only outputs a string, it does not output any HTML. This makes it different from the Rich Text field which can output formatted HTML.
Assign the Key Text field a Field name, API ID, and Field placeholder that will display in the entry editor.
The following allows you to input a simple string:
"label": "Product Description",
"placeholder": "Enter the product description..."
"type": (string, required) Value must equal "Text"
"config": (object, optional) Options listed below
"placeholder": (string) Sets a user-friendly placeholder into the field
"label": (string) Sets the label that shows up for the field in the entry editor
"useAsTitle": (boolean) If set to true, will use this field for the document name on the document listing page
