+TanStack Hotkeys includes utilities for turning hotkey strings into display-friendly labels. These utilities are framework-agnostic and are re-exported from `@tanstack/ember-hotkeys`.
+
+## `formatForDisplay`
+
+```ts
+import { formatForDisplay } from '@tanstack/ember-hotkeys';
+
+formatForDisplay('Mod+S');
+// Mac: "⌘S"  |  Windows: "Ctrl+S"
+
+formatForDisplay('Mod+Shift+Z');
+// Mac: "⌘⇧Z"  |  Windows: "Ctrl+Shift+Z"
+```
+
+## `formatWithLabels`
+
+```ts
+import { formatWithLabels } from '@tanstack/ember-hotkeys';
+
+formatWithLabels('Mod+S');
+formatWithLabels('Mod+Shift+Z');
+```
+
+## Using in Templates
+
+### Keyboard Shortcut Badges
+
+```gts
+import { formatForDisplay } from '@tanstack/ember-hotkeys';
+import onHotkey from '@tanstack/ember-hotkeys/helpers/on-hotkey';
+
+<template>
+  {{onHotkey "Mod+S" @onSave}}
+  <button type="button">
+    Save <kbd>{{formatForDisplay "Mod+S"}}</kbd>
+  </button>
+</template>
+```
+
+### Menu Items with Hotkeys

+```gts
+import { formatForDisplay } from '@tanstack/ember-hotkeys';

+---
+
+TanStack Hotkeys provides the `HotkeyRecorder` class for building shortcut customization UIs. The class is re-exported from `@tanstack/ember-hotkeys` and can be used directly in Ember components.
+
+## Basic Usage
+
+```gts
+import Component from '@glimmer/component';
+import { tracked } from '@glimmer/tracking';
+import { action } from '@ember/object';
+import { HotkeyRecorder, formatForDisplay } from '@tanstack/ember-hotkeys';
+import type { Hotkey } from '@tanstack/ember-hotkeys';
+
+export default class ShortcutRecorder extends Component {
+  @tracked recordedHotkey: Hotkey | null = null;
+  @tracked isRecording = false;
+
+  recorder = new HotkeyRecorder({
+    onRecord: (hotkey) => {
+      this.recordedHotkey = hotkey;
+      this.isRecording = false;
+    },
+    onCancel: () => {
+      this.isRecording = false;
+    },
+  });
+
+  @action startRecording() {
+    this.recorder.start();
+    this.isRecording = true;
+  }
+
+  @action cancelRecording() {
+    this.recorder.cancel();
+  }
+
+  <template>
+    <button type="button" {{on "click" this.startRecording}}>
+      {{#if this.isRecording}}
+        Press a key combination...
+      {{else if this.recordedHotkey}}
+        {{formatForDisplay this.recordedHotkey}}
+      {{else}}
+        Click to record
+      {{/if}}
+    </button>
+    {{#if this.isRecording}}
+      <button type="button" {{on "click" this.cancelRecording}}>Cancel</button>
+    {{/if}}
+  </template>
+}
+```
+
+## `ignoreInputs`
+
+The `HotkeyRecorder` supports an `ignoreInputs` option (defaults to `true`). When `true`, the recorder will not intercept normal typing in text inputs, textareas, selects, or contentEditable elements — keystrokes pass through to the input as usual. Pressing **Escape** still cancels recording even when focused on an input.
+
+```ts
+const recorder = new HotkeyRecorder({
+  ignoreInputs: false, // record even from inside inputs
+  onRecord: (hotkey) => console.log(hotkey),
+});
+```

+title: Hotkeys Guide
+id: hotkeys

+
+The `{{onHotkey}}` helper is the primary way to register keyboard shortcuts in Ember applications. It wraps the singleton `HotkeyManager` with Ember's helper lifecycle: when the helper enters the template the key is registered, and when the template is torn down the listener is removed.
+
+## Basic Usage
+
+```gts
+import onHotkey from '@tanstack/ember-hotkeys/helpers/on-hotkey';
+
+const save = () => {
+  saveDocument();
+};
+
+<template>
+  {{onHotkey "Mod+S" save}}
+</template>
+```
+
+The callback receives the original `KeyboardEvent` as the first argument and a `HotkeyCallbackContext` as the second:
+
+```gts
+import onHotkey from '@tanstack/ember-hotkeys/helpers/on-hotkey';
+
+const save = (event: KeyboardEvent, context: HotkeyCallbackContext) => {
+  console.log(context.hotkey);
+  console.log(context.parsedHotkey);
+};
+
+<template>
+  {{onHotkey "Mod+S" save}}
+</template>
+```
+
+## Options
+
+All options are passed as named arguments in the template:
+
+```gts
+{{onHotkey "Mod+S" @onSave
+  preventDefault=true
+  stopPropagation=true
+  eventType="keydown"
+  enabled=true
+}}
+```
+
+### `enabled`
+
+When `enabled` is false, the hotkey **stays registered** (visible in devtools); only the callback is suppressed.
+
+```gts
+import onHotkey from '@tanstack/ember-hotkeys/helpers/on-hotkey';
+
+<template>
+  {{onHotkey "Escape" @onClose enabled=@isOpen}}
+</template>
+```
+
+### `target`
+
+Scope a hotkey to a specific DOM element instead of the entire document:
+
+```gts
+import onHotkey from '@tanstack/ember-hotkeys/helpers/on-hotkey';
+
+<template>
+  <div tabindex="0" {{onHotkey "Escape" @onClosePanel target=this}}>
+    Panel content
+  </div>
+</template>
+```
+
+### `preventDefault`
+
+Prevent the browser default action (e.g., browser save dialog for `Mod+S`). This is `true` by default.
+
+```gts
+{{onHotkey "Mod+S" @onSave preventDefault=true}}
+```
+
+### `stopPropagation`
+
+Stop the event from propagating to parent elements:
+
+```gts
+{{onHotkey "Escape" @onClose stopPropagation=true}}
+```
+
+### `eventType`
+
+Listen for `keyup` events instead of the default `keydown`:
+
+```gts
+{{onHotkey "Escape" @onClose eventType="keyup"}}
+```
+
+### `requireReset`
+
+When `true`, the hotkey fires at most once per key-hold. The user must release the key and press again to fire the callback a second time.
+
+```gts
+{{onHotkey "Escape" @onClose requireReset=true}}
+```
+
+### `ignoreInputs`
+
+By default, hotkeys are suppressed when an input element is focused. Set `ignoreInputs` to `false` to fire the callback even when an input, textarea, or contenteditable element has focus:
+
+```gts
+{{onHotkey "Enter" @onSubmit ignoreInputs=false}}
+```
+
+### `conflictBehavior`
+
+Control what happens when the same hotkey is registered twice:
+
+```gts
+{{onHotkey "Mod+S" @onSave conflictBehavior="replace"}}
+```
+
+### `platform`
+
+Force a specific platform for `Mod` resolution:
+
+```gts
+{{onHotkey "Mod+S" @onSave platform="mac"}}
+```
+
+## Metadata (name & description)
+
+Every hotkey registration can carry a `meta` object with a `name` and `description`. This metadata is informational only -- it does not affect hotkey behavior -- but it flows through to registrations and devtools, making it easy to build shortcut palettes and help screens.
+
+```gts
+{{onHotkey "Mod+S" @onSave meta=(hash name="Save" description="Save the document")}}
+```
+
+## Automatic Cleanup
+
+Registrations are cleaned up automatically when the helper is destroyed -- for example, when the component is removed from the DOM or when an `{{#if}}` block becomes falsy.
+
+## The Hotkey Manager
+
+You can access the underlying manager directly when needed:
+
+```ts
+import { getHotkeyManager } from '@tanstack/ember-hotkeys';
+
+const manager = getHotkeyManager();
+manager.isRegistered('Mod+S');
+manager.getRegistrationCount();
+```
