Hello, Since the full keyboard access Help menu is a little vague on the nuances between Tab, arrow keys, and Ctrl+tab in terms of navigation, could you point me to where I can find the intended mapping of FKA keys to UI elements? For example, I have been in several Apple iOS apps where the UITabBar at the bottom is navigable with any of the three options mentioned above. In other contexts, the tab key only moves the user to the tab bar section, then the icons are focusable with arrow or Ctrl + tab. When a modal pops up stating I will be leaving an app, should the choices be navigable with Tab? Ctrl+tab? or arrows too? In other places, like news articles in Apple News, it seems that I cannot scroll with the arrow keys to read the various paragraphs, nor interact with links at all that are in the article. If there is a separate keyboard shortcut for links or scrollbar, please update the Help menu. It seems pretty straightforward that arrow keys navigate between HStacks and VStacks. Is that an accurate guess of arrow key behavior? I feel like I'm guessing in several places within the content groups.

I'm testing Full Keyboard Access in my app and on the iPhone apps in my iPhone 12 mini with OS 17. My work will directly impact how much accessibility review is done on our iOS app which has millions of unique views a month. In several Apple apps I cannot seem to scroll down through the screen when the main View has focus. For example, the Home app does not scroll with arrow keys nor Ctrl+tab through any of the 6 main content groups on the Discover screen. it almost appears it's a single static image; the "Getting Started" button is not able to be activated. I can activate sections further down when I enable gestures, but cannot pinpoint a specific location. The Stocks app includes Top Stories from the Apple News app; in either app I can select a story, which brings up the article on full screen, but then I cannot use the arrow keys or Ctrl+tab to read the article or interact with inline links. Ctrl + tab selects the button features like to watch an embedded video or live coverage, then jumps down to the end of the article to focus on Related stories, ignoring all the links in between. I am able to somewhat move through the article text with keyboard gestures, but many of these articles have embedded links or content after the article (before "Related Stories" I work in digital accessibility and need to be able to tell my teams what is expected behavior and where to see examples of this. If Apple can't demonstrate Full Keyboard Access in its own apps this is a problem. Our own app has some of these issues but I am unsure how to recommend a solution when the scrollview seems to not work in native iOS apps by Apple.
