Onboarding · Help: help panel, cheatsheet, what's new, feedback, support, inline help

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.

 - gpui clicks a focused element when Enter or Space is released. An overlay that hands focus back picks on release too; a pick on press returns focus first, and the release clicks the opener again. An edit in place that hands focus back keeps its text on Enter's release (`forms::InlineEdit`). The press itself bubbles, so a container that takes Space leaves a focused button its own: `overlays::media_button` stops it, and a button in a `SelectableList` row stops Space and Enter at its box (`mail::MailItem`'s star, `messaging::PinnedMessages`' Unpin).
 - A focus handle a component hands back lives across all its modes: take it with `tab_stop` before any early return, or keyed state drops it while the other mode draws and the handed-back focus lands nowhere. A thread's message keeps one handle folded and open, a Tab stop only while folded (`mail::MailThreadView`).
 - A button whose words and action change with a mode keeps one handle through `Button::focus_handle`, and the component moves focus to it or back to its field as the mode turns (`project::TimeTracker`).
+- A button that waits on the owner shows it with `loading`, which takes no press and stays a Tab stop, so focus holds through the wait; `disabled` is for what is not ready, and a disabled button is no stop (`onboarding::ContactSupport`).
+- A help mark, ?, is `primitives::HelpTooltip`; FormLabel's help shows it.
 - A panel that opens from something other than a button goes through `overlays::Popover::with_opener`, which hands the opener its toggle; focus, placement and every way out stay in the popover (`calendar::EventPopover`'s chip). Its content gets a close that hands focus back: a press that ends the panel's work closes it before the owner acts, or a panel whose host leaves the tree strands focus (`onboarding::Hotspot`'s Got it, EventPopover's Edit and Delete).
 - A flow in steps goes through `navigation::Wizard`: Back, Next, Finish and the step's motion live there. Next and Finish share one focus handle, and focus moves to it when Back reaches the first step or a finished step is picked. `onboarding::OnboardingWizard` leaves out its numbered steps (`headless`) and shows a count over a bar in as many parts.
 - A dialog goes through `overlays::Dialog`: scrim, focus trap, Escape and focus return live there. Its close runs on every way out, so a dialog with two answers marks the chosen one before it closes (`messaging::IncomingCallDialog`). AlertDialog, ConfirmDialog and PromptDialog build on it; a fullscreen dialog fills the window below its title bar. A dialog's card fits the window, a title bar's height clear at each end; its body scrolls and its actions stay.
