HelpPanel lists its articles in lists::SelectableList: the list is one
stop whose cursor scrolls into view, and Enter or a double press opens
an article, focus going to All articles as before. SelectableList now
activates on Enter's release, armed by its own press, as the palette
and menus pick: an activation that moves focus left the release to
press what took it, here the way back. ContactSupport cuts a long
address in the middle and puts a Copy beside it. The lists tests move
into a folder, the release tests on their own.
HelpPanel searches articles and opens one, its body in Markdown, with a
way back; focus follows to All articles and back to the search, a
link to help:<key> opens another, and Contact support and Keyboard
shortcuts wait at its foot. KeyboardShortcutCheatsheet puts
settings::KeyboardShortcutsList in a dialog with its search focused;
WhatsNewDialog puts data_display::Changelog in one with Got it.
FeedbackWidget asks how it is going with four faces and a note, and
thanks. ContactSupport sends a topic and a message, spins while the
owner sends, and empties the message with focus back in it. InlineHelp
is a quiet line with Learn more. HelpTooltip moves to primitives,
where FormLabel's help mark shows it; ToggleGroup keys its toggles by
its own id. EmptyStateWithAction points to feedback::EmptyState.
