Event Handler

• keydown (as default)
• keyup

Key Combination

Use one or more of following keys to fire your hotkeys.

• ctrl
• alt
• shift

• windows (Windows)

Modifiers

prevent

Add the prevent modifier to the directive to prevent default browser behavior.

<template>
  <span v-hotkey.prevent="keymap" v-show="show">
    Press `ctrl + esc` to toggle me! Hold `enter` to hide me!
  </span>
</template>

stop

Add the stop modifier to the directive to stop event propagation.

<template>
  <div v-hotkey.stop="keymap">
    <span>
      Enter characters in editable areas doesn't trigger any hotkeys.
    </span>
    <input />
  </div>
</template>

forbidden

Add the forbidden modifier to the directive to allow hotkeys in forbidden elements (i.e. inputs, textfields).

<template>
  <div v-hotkey.forbidden="keymap">
    <span> Enter characters in editable areas does trigger hotkeys. </span>
    <input />
  </div>
</template>
