#Notes

The one place that knows which keys are bound, so the sheet on ? and the handlers cannot disagree. shortcuts is the list left live by the site's shortcuts.singleCharacter policy, keys() draws one for the reader's own keyboard (⌘ or Ctrl), and on() binds an action with every guard a global binding needs — never while the reader is typing, never inside a dialog or menu, never once something nearer has handled the key, and, for the unmodified keys, only while the page's own content holds focus.

hint() is keys() for a control rather than for the sheet: it takes an action, returns the keys as one string — ⌘K, Ctrl+K, ] — and returns undefined where the policy unbound that action, so a template writes v-if and draws no empty key cap. It is what the search button and the adjacent-page links print.

useDuxtShortcutSheet() is the sheet's open state, shared rather than owned by the sheet, because ? is not the only way in: the header's trigger opens the same dialog, and on a site with shortcuts.singleCharacter: false it is the only thing that can. See Keyboard shortcuts.
