Modifiers

prevent

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

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