3.2.1 — On Focus
Level A Understandable
Operational summary
IF a control gains focus, do not initiate a change of context merely because of focus. Opening a new page or submitting a form is different from a local content reveal; assess the actual effect.
This is an original implementation summary, not replacement normative text. The sources below supply the precise requirement, its definitions and its qualifications.

Registry record
Applicability and assessment start unset by design — no product has been evaluated. Instantiate the entry for an actual product, assign an owner and retain evidence.
