Shortcuts

Some components like Dropdown, Command Palette and Tooltip support the display of keyboard shortcuts.

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

Shortcuts are displayed and styled through the Kbd component.

<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.

<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>

Shortcuts keys are written as the literal keyboard key value. Combinations are made with _ separator. Chained shortcuts are made with - separator.

Modifiers are also available:

• meta: acts as Command for MacOS and Control for others
• ctrl: acts as Control
• shift: acts as Shift and is only necessary for alphabetic keys

Examples of keys:

• escape: will trigger by hitting Esc
• meta_k: will trigger by hitting ⌘ and K at the same time on MacOS, and Ctrl and K on Windows and Linux
• ctrl_k: will trigger by hitting Ctrl and K at the same time on MacOS, Windows and Linux
• shift_e: will trigger by hitting Shift and E at the same time on MacOS, Windows and Linux
• ?: will trigger by hitting ? on some keyboard layouts, or for example Shift and /, which results in ? on US Mac keyboards
• g-d: will trigger by hitting g then d with a maximum delay of 800ms by default
• arrowleft: will trigger by hitting ← (also: arrowright, arrowup, arrowdown)

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.

<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.

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.

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

useShortcuts

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

<script setup lang="ts">
const { metaSymbol } = useShortcuts()
</script>

<template>
  <UKbd>{{ metaSymbol }}</UKbd>
</template>

metaSymbol will display either ⌘ on MacOS or Ctrl on any other OS
