Interface: FieldActions

JavaScript actions attached to a form field.

Key mapping (ISO 32000-2 Table 217):

• keystroke → /K (Keystroke action)
• format → /F (Format action)
• validate → /V (Validate action)
• calculate → /C (Calculate action)

Each string is raw PDF JavaScript source code. The library emits each non-null action as a PDF stream object referenced from the /AA dictionary on the field annotation.
