I use Vue.js
It is necessary that when you click anywhere on the page of a particular key (or key combination), for example, Del or Backspase, a click handler is invoked.
How can this be implemented using Vue.js?
Events, like @keydown, work, as I understand it, only in the input fields.

    You can, for example, add an input field, place it outside of the scope (for example, absolute and top = -100), then, when loading and clicking on the page, transfer focus to it.

    It is important that the focus is not transferred when clicking on any form, but it will be inconvenient. To do this, you can track the class name of the element you clicked.

    Example:

    var container = new Vue({ el: '#app', mounted() { this.setInputFocus() document.onclick = this.setInputFocus }, data: () => ({ lastKey: '' }), methods: { setInputFocus(e = {path: []}) { if (e.path[0]) { if (e.path[0].classList[0] == 'form') { return; } } window.focusText.focus() }, setLastKey(e) { focusText.value = "" this.lastKey = e.key } } }); 
     div { margin: 10px 0px; } 
     <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.min.js"></script> <div id=app> <input type="text" id="focusText" @keydown="setLastKey"> <div> {{lastKey}} </div> <div> Lorem ipsum dolor sit amet, consectetur adipiscing elit.
