Transcript: scripted keyboard navigation demo

1. [00:00:00.000] Scripted keyboard navigation demo (automated). Not a screen reader demonstration: VoiceOver automation is unavailable on macOS 27, so no spoken output is shown. Captions describe the scripted keyboard steps.
2. [00:00:05.454] The module home page loads. Every page starts with a skip link as the first tab stop.
3. [00:00:05.926] Tab once — the skip link receives a visible focus outline.
4. [00:00:06.256] Enter activates the skip link; focus jumps past the navigation to the main content.
5. [00:00:06.517] Tab moves through the module navigation links.
6. [00:00:06.775] Enter opens the Lesson page.
7. [00:00:07.035] The lesson page: the study outline as semantic HTML with headings, lists, and a data table with a caption and scoped headers.
8. [00:00:10.688] Tab reaches the Schools of Psychological Thought table; row and column headers are announced to assistive technology via scope attributes.
9. [00:00:10.947] Arrow keys move between row headers in the table.
10. [00:00:11.201] Next: the lecture slides page, where the 54-slide deck is HTML with real text, figure descriptions, and speaker notes.
11. [00:00:11.487] Tab through the page; a details element expands the long description of a visual.
12. [00:00:11.745] Enter expands the long description of the slide’s visual.
13. [00:00:12.013] The expanded long description is visible to sighted users and read by screen readers alike.
14. [00:00:15.676] The video page: a standard video element with a captions track, chapter buttons, and a transcript link.
15. [00:00:16.146] Tab to a chapter button.
16. [00:00:16.397] Enter starts playback from that chapter — the video element is fully keyboard operable.
17. [00:00:16.651] The player controls are native and keyboard accessible; captions load from the transcript-derived WebVTT file.
18. [00:00:21.503] Last: the practice quiz.
19. [00:00:21.856] Tab to the first question’s radio group.
20. [00:00:22.154] Arrow keys move within the radio group — radios use arrow-key navigation.
21. [00:00:22.408] Space selects an answer.
22. [00:00:22.661] Tab to the Check answer button.
23. [00:00:22.911] Enter checks the answer; feedback appears in a live region that assistive technology announces.
24. [00:00:23.164] Textual feedback is shown — never color alone. The score region updates politely.
25. [00:00:29.016] Every check shown here is scripted; see the case study’s evidence section for the full audit, and the limitations section for what remains pending — including a human VoiceOver pass and a review by a daily assistive-technology user.
