Function: createHotkey()

function createHotkey(
   hotkey, 
   callback, 
   options): void;

Defined in: createHotkey.ts:83

SolidJS primitive for registering a keyboard hotkey.

Uses the singleton HotkeyManager for efficient event handling. The callback receives both the keyboard event and a context object containing the hotkey string and parsed hotkey.

This primitive automatically tracks reactive dependencies and updates the registration when options or the callback change.

Parameters

hotkey

The hotkey string (e.g., 'Mod+S', 'Escape') or RawHotkey object (supports mod for cross-platform)

RegisterableHotkey | () => RegisterableHotkey

callback

HotkeyCallback

The function to call when the hotkey is pressed

options

Options for the hotkey behavior

CreateHotkeyOptions | () => CreateHotkeyOptions

Returns

void

Examples

tsx

function SaveButton() {
  const [count, setCount] = createSignal(0)

  // Callback always has access to latest count value
  createHotkey('Mod+S', (event, { hotkey }) => {
    console.log(`Save triggered, count is ${count()}`)
    handleSave()
  })

  return <button onClick={() => setCount(c => c + 1)}>Count: {count()}</button>
}

tsx

function Modal(props) {
  // enabled option is reactive
  createHotkey('Escape', () => {
    props.onClose()
  }, () => ({ enabled: props.isOpen }))

  return <Show when={props.isOpen}>
    <div class="modal">...</div>
  </Show>
}

tsx

function Editor() {
  const [editorRef, setEditorRef] = createSignal<HTMLDivElement | null>(null)

  // Scoped to a specific element - use accessor so hotkey waits for ref
  createHotkey('Mod+S', save, () => ({ target: editorRef() }))

  return <div ref={setEditorRef}>...</div>
}
