hope it helps you.

doSomething(){
  console.log('clicked')
}

var buttonBtn = document.getElementById("btn");
buttonBtn.addEventListener("keyup", function(event) {
  event.preventDefault();
  this.doSomething();
});

<button id="btn" @click="doSomething()"> PRESS ME </button>

You can use onkeyrinkle from vueuse

<template>
  <div>
    <button @click="doSomething">btn</button>
  </div>
</template>

<script setup>
import { onKeyStroke } from '@vueuse/core';

const doSomething = () => {
  console.log('do something');
}

onKeyStroke(['ArrowUp'], (e) => {
  doSomething();
});
</script>

Here is another demo一个>

stackblitz.com does not support , so in this demo it is written with setup()

renew

Pure js without libraries:

<template>
    <div>
        <button
            @click="doSomething">
            btn
        </button>
    </div>
</template>

<script setup>
import { onMounted, onBeforeUnmount } from 'vue';

const doSomething = () => {
    console.log('doSomething');
};

const userClickArrowUp = ({ code }) => {
    if (code === 'ArrowUp') {
        doSomething();
    }
};

onMounted(() => {
    document.addEventListener('keyup', userClickArrowUp, true);
})

onBeforeUnmount(() => {
    document.removeEventListener('keyup', userClickArrowUp, true);
})

</script>
