Sequence Recording Guide

Use createHotkeySequenceRecorder to capture a series of shortcut chords. By default, each step records its physical code: pressing G twice produces ['[KeyG]', '[KeyG]']. Set recordBy: 'key' to follow logical characters instead. Pass the resulting array directly to sequence registration and format each step for display.

Record and display a sequence#

This example uses a Save button so plain Enter can be recorded as a step:

<script lang="ts">
  import { createHotkeySequenceRecorder, formatForDisplay } from '@tanstack/svelte-hotkeys'

  const recorder = createHotkeySequenceRecorder({
    commitKeys: 'none',
    onRecord: (sequence) => console.log('Register or persist:', sequence),
    onReject: ({ message }) => console.log(message),
  })
  const displayedSteps = $derived(recorder.isRecording ? recorder.steps : recorder.recordedSequence ?? [])
</script>

<button onclick={recorder.startRecording}>Record sequence</button>
<p>{displayedSteps.map((step) => formatForDisplay(step)).join(' → ')}</p>
{#if recorder.isRecording}
  <button onclick={recorder.commitRecording}>Save</button>
  <button onclick={recorder.cancelRecording}>Cancel</button>
{/if}

State and controls#

The recorder exposes isRecording, steps, and recordedSequence as reactive getters. steps contains the current attempt; recordedSequence contains the last committed result. startRecording() begins a new session. commitRecording() saves a nonempty attempt, while cancelRecording() discards it and calls onCancel. stopRecording() resets recorder state without calling onRecord or onCancel.

Options and keyboard behavior#

• recordBy: 'code' by default; 'key' records produced logical characters.
• commitKeys: 'enter' by default; plain Enter commits a nonempty sequence. 'none' lets Enter become a step and requires manual or idle commit.
• commitOnEnter: false: also permits Enter as a step when commitKeys is 'enter'.
• idleTimeoutMs: optionally commits after inactivity following a completed step. No timer runs before the first step.
• ignoreInputs: true by default, including shadow-root inputs. Set false to record from editable fields. Escape still cancels from an input.

Escape cancels. Unmodified Backspace/Delete removes the last step; when already empty it stops and calls only onClear. Modifier-only presses, automatic repeats, and IME composition do not append steps. Recorded events and their releases do not trigger application shortcuts.

Set provider defaults through HotkeysProvider with defaultOptions.hotkeySequenceRecorder.

Validation and conflicts#

validate(sequence, { events, parsedSequence }) runs at commit. Return true to accept, or false/a message to reject. detectConflicts checks live bindings and sequence prefixes, including physical/logical overlap established by the recorded events. onReject receives feedback; rejected steps remain editable with Backspace.

The shared options and exclusions are described in the hotkey recording guide. The application owns reset, persistence, and any binding being edited; clearing never calls onRecord([]).
