Use the correct device branch
HBO Max’s UK guide documents external-keyboard navigation on web, phones and tablets, then separately describes keyboards on streaming players and games consoles. For the latter group it lists arrows for navigation and Enter for selection while saying keyboard shortcuts are not available. A connected keyboard is therefore not a universal promise of identical hotkeys.
Separate focus movement from transport
If arrows reach a programme card but a memorised playback shortcut does nothing, record both results. The first is evidence of navigation; the second may reflect the documented shortcut limit. Do not treat the working card selection as proof that every keyboard action used in a desktop tutorial should also work on the living-room client.
Use a harmless control comparison
Test a labelled non-purchase control using the supported navigation and selection method. Preserve the viewer’s access setup and inspect the actual focus indication. On a phone or tablet, follow the device’s relevant keyboard-access instructions rather than assuming a games-console rule applies there too.
Report the access need accurately
Include the device, connected keyboard, control reached and action attempted. If a necessary function cannot be operated through the supported method, describe that barrier to the publisher. An unsupported shortcut is not evidence that the account expired, and resetting the network does not add a keyboard feature the client does not implement.
Keep PS5 screen-reader support scoped to menus
HBO Max’s UK accessibility guide qualifies PlayStation 5 Screen Reader support as menu navigation. An announced menu item therefore does not establish that every playback control or programme detail will be spoken. Check the actual task the viewer needs to complete and distinguish screen-reader navigation from a title’s separate Audio Description track. Preserve successful menu navigation and any remaining playback barrier as different observations when describing the access requirement.
Questions, answered
Are all desktop shortcuts promised on console clients?
No. HBO Max explicitly qualifies that support.
Does successful arrow navigation prove every hotkey works?
No. Navigation and shortcuts are separate capabilities.
