Preserve the user’s access method
Narrator users may navigate a page through reading commands rather than ordinary direct keyboard shortcuts. Microsoft describes scan mode as a navigation and reading mode for apps, email and webpages. Start with the access setup already in use, and choose a harmless labelled control or text field for the comparison.
Identify the mode deliberately
Microsoft documents Narrator plus Spacebar for toggling scan mode, with Caps Lock or Insert acting as the default Narrator modifier. Read the announcement and current setup rather than assuming a particular key has its ordinary browser function. Do not change customised access preferences without noting the arrangement needed to restore them.
Separate navigation and editing
In scan mode, arrow keys navigate and Enter or Spacebar can activate an item. Microsoft also documents automatic mode changes around edit fields so text can be entered. A key that moves reading focus in one context may therefore type or control something else after focus changes; describe the actual element and announced state.
Report a concrete access barrier
Record whether the intended control was reached, had a meaningful label and responded to the appropriate activation command. A missing accessible label and a service error after successful activation are different failures. Do not infer a complete accessibility pass from one working button, or disable Narrator permanently as a substitute for addressing a task the viewer needs.
Questions, answered
Why can arrow keys navigate text instead of controlling playback?
Their role can depend on Narrator scan mode and current focus.
Does one reachable button establish full player accessibility?
No. Evaluate the actual tasks and controls required.
