⚠️ W3C Working Draft Notice

WCAG 3.0 is an active W3C Working Draft in development by the AGWG. Requirements, assertions, the conformance model and reporting tiers are still being developed and may change. The latest published draft is the 10 September 2026 Working Draft; this site follows the editors’ draft, which also includes exploratory provisions.

developing Supplemental requirement

Navigation Keys Described

Group: input-operation • Guideline: physical-or-cognitive-effort-when-using-keyboard

Summary in Plain English

If understanding or operating the page needs a keyboard action that is not a common navigation technique, it is described on that page or earlier in the process.

Why It Matters

Custom interaction models are not discoverable by exploration. Without a description, a keyboard user has no way to know the technique exists.

Scope: When This Applies

The draft's own conditions, quoted from guidelines/groups/input-operation/physical-or-cognitive-effort-when-using-keyboard/navigation-keys-described.md.

Notes in the draft

Any platform-related functions are not the responsibility of the author as long as they are not overridden by the content. Examples:

  • Tab and Shift + Tab to move through elements
  • Sticky Keys functionality that allows single key activation of multi-key commands
