F2 — Vim-style keyboard shortcuts (the audit's F2 / H7 finding).
New files:
- frontend/src/hooks/useKeyboardShortcuts.ts: lightweight global
handler. Supports both single keys ('/', '?', 'Escape') and
vim-style 2-key sequences ('g d', 'g r', 'g p', 'g s' for nav).
Sequence timeout is 1500ms; pending prefix is cleared on any
unrecognised key so typing 'g' alone is safe. Suppressed when
the user is typing in an input/textarea/select/contenteditable,
or when any modifier key (Ctrl/Cmd/Alt) is held — those chords
belong to the browser or other handlers. Uses a ref so the
listener is registered once and always sees the latest callbacks.
- frontend/src/hooks/useFocusSearch.ts: tiny CustomEvent bus.
requestFocusSearch() dispatches a 'mealplanner:focus-search'
event; useFocusSearchOnShortcut(ref) subscribes and focuses the
supplied input. The decoupling lets any page opt in without the
global handler needing to know the page's DOM.
- frontend/src/components/ShortcutHelpBanner.tsx: dismissible help
dialog that slides down under the nav when '?' is pressed.
Auto-dismisses after 6s; Escape also dismisses. role=dialog +
aria-label for screen readers; the kbd elements use the
<kbd> semantic for assistive tech.
Wired in App.tsx:
- New <GlobalShortcuts /> child of <BrowserRouter> calls
useKeyboardShortcuts with the 4 nav sequences, '/' →
requestFocusSearch(), and '?' → dispatch SHOW_SHORTCUT_HELP_EVENT.
- <ShortcutHelpBanner /> mounted inside the page wrapper (after
<main>).
Pantry and Recipes now call useFocusSearchOnShortcut with a
forwardRef attached to their top search inputs. Recipes's search
already debounced via handleSearch so focusing just selects the
existing text for the user to replace. Pantry's search is a plain
controlled input, same treatment.
Behaviour summary:
- g d / g r / g p / g s → navigate to the 4 main pages
- / → focus the search input on the current page (Pantry + Recipes
only — other pages have no search)
- ? → show the help banner
- All shortcuts are no-ops inside text-entry controls, so a user
typing 'p' into the pantry search box will not trigger navigation.
