Form operators

Form operators can be divided into several categories:

• Value input - operators responsible for inputting a value.
• Object group operators - operators that operate on an object group of a form.
• Focus operators - operators that manage the activity of form elements and report on it.
• Capture - an operator that creates an action capturing the currently rendered visual state of the user interface.
• Container visibility - operators that create actions controlling the visibility of the contents of collapsible containers of a form.
