Duplicate access keys cause conflicts where only one element (usually the first) is reachable via the shortcut, making other elements inaccessible to keyboard users.
accesskey attribute value must be unique on the pageCheck for duplicate accesskey attributes across the document to ensure each shortcut is unique.
Assign unique values to each accesskey attribute or remove redundant ones to prevent shortcut conflicts.
Explain how duplicate access keys affect keyboard accessibility and browser shortcut handling.
Review the rendered markup and interactive states that affect Ensure accesskey values are unique. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
