useHotkeys

function useHotkeys(hotkeys, commonOptions?): void;

Defined in: useHotkeys.ts:59

Preact hook for registering several hotkeys at once: chords, sequences, and app hotkeys. Accepts a dynamic array, so it is safe to use with variable-length lists without violating the rules of hooks.

Options merge in this order: provider defaults, app hotkey declaration, commonOptions, per-hotkey options. Each option applies only to the kinds that support it. Callbacks and options sync on every render.

Per-row enabled: false keeps that registration (visible in devtools) and only suppresses firing. Unbound app hotkeys and empty sequences register nothing.

Parameters#

hotkeys#

readonly UseHotkeyDefinition[]

Hotkeys to register

commonOptions?#

UseHotkeyCommonOptions = {}

Options applied to every hotkey (overridden by per-hotkey options)

Returns#

void

Examples#

function Editor() {
  useHotkeys([
    { hotkey: 'Mod+S', callback: () => save() },
    { hotkey: ['G', 'G'], callback: () => scrollToTop(), options: { timeout: 500 } },
    { hotkey: 'Escape', callback: () => close() },
  ])
}

function MenuShortcuts({ items }) {
  // Dynamic hotkeys from data -- safe because it's a single hook call
  useHotkeys(
    items.map((item) => ({
      hotkey: item.shortcut,
      callback: item.action,
      options: { enabled: item.enabled },
    })),
    { preventDefault: true },
  )
