## Overview

Some components like [Dropdown](/elements/dropdown), [Command Palette](/navigation/command-palette) and [Tooltip](/overlays/tooltip) support the display of keyboard shortcuts.

```vue
<UDropdown :items="[{ label: 'Edit', shortcuts: ['E'] }]" />
```

Shortcuts are displayed and styled through the [Kbd](/elements/kbd) component.

```vue
<template>
  <div class="flex items-center gap-0.5">
    <UKbd>⌘</UKbd>
    <UKbd>K</UKbd>
  </div>
</template>
```

## `defineShortcuts`

This module provides a `defineShortcuts` composable that allows you to define keyboard shortcuts in your app really easily.

```vue
<template>
  <UModal v-model="isOpen" />
</template>

<script setup lang="ts">
const isOpen = ref(false)

defineShortcuts({
  meta_k: {
    usingInput: true,
    handler: () => {
      isOpen.value = !isOpen.value
    }
  }
})
</script>
```

### `usingInput`

Prop: `usingInput?: string | boolean`

By default, `usingInput` is `false`, meaning it will only trigger when no input is focused. When set to `true`, the shortcut will also trigger when any input is focused.

For a more advanced behavior, `usingInput` can be set to the name of an input, so it only triggers when focusing this specific input.

```vue
<template>
  <UInput v-model="query" name="queryInput" />
</template>

<script setup lang="ts">
const query = ref('')

defineShortcuts({
  enter: {
    usingInput: 'queryInput',
    handler: () => {
      // TODO
    }
  }
})
</script>
```
_`enter` shortcut will only trigger when `queryInput` is focused._

### `whenever`

Prop: `whenever?: WatchSource<Boolean>[]`

`whenever` allows to add constraints on the shortcut triggering behavior. This array can contain `Ref<Boolean>`, `ComputedRef<Boolean>` or `() => Boolean`.

```ts
defineShortcuts({
  meta_k: {
    usingInput: true,
    handler: () => { isOpen.value = !isOpen.value }
  },
  escape: {
    usingInput: true,
    whenever: [isOpen],
    handler: () => { isOpen.value = false }
  }
})
```
_`escape` shortcut will only trigger when `isOpen` is `true`._

### Simple shortcut

In case the shortcut does not need any config, it can be written as a function.

```ts
defineShortcuts({
  '?': () => openHelpModal()
})
```

## `useShortcuts`

To display shortcuts in your app according to the user's OS, you can use the `useShortcuts` composable.

```vue
<script setup>
const { metaSymbol } = useShortcuts()
</script>

<template>
  <UKbd>{{ metaSymbol }}</UKbd>
</template>
```
_`metaSymbol` will display either `⌘` on MacOS or `Ctrl` on any other OS_
