Our app supports Full Keyboard Access. We have a scroll view containing content that extends beyond the visible area. When navigating with the keyboard, focusable elements inside the scroll view are reached and the view scrolls to follow focus, but content that has no focusable elements (e.g. long blocks of static text, images, or footer content below the last control) can't be brought into view by the keyboard alone.
Is there a supported way for Full Keyboard Access users to scroll a scroll view to see this off-screen, non-focusable content — e.g. a built-in scroll command, or an API to make the scroll view itself focusable/scrollable via the keyboard — without resorting to custom key handling?
