This technique relates to Success Criterion 3.2.2: On Input (Sufficient as a way to meet G80: Providing a submit button to initiate a change of context).
The objective of this technique is to provide a mechanism that allows users to explicitly request a change of context using the submit-form action in a PDF form. The intended use of a submit button is to generate an HTTP request that submits data entered in a form, so it is an appropriate control to use for causing a change of context. In PDF documents, submit buttons are normally implemented using a tool for authoring PDF.
Examples 1 and 2 demonstrate how to add a submit button using specific authoring tools. There are other PDF tools that perform similar functions. Check the functionality provided by .
