Keyboard Navigation

The Rich Text Editor component followed the keyboard interaction guideline, making it easy for people who use assistive technologies (AT) and those who completely rely on keyboard navigation. The following keyboard shortcuts are supported by the Rich Text Editor component.

For more details on keyboard navigation, refer to the Keyboard support documentation.

Customizing Shortcut Keys

You can customize shortcut keys using the formatter property.This allows you to configure custom key combinations for various actions in the Rich Text Editor. For example, you can set ctrl+q to open the Insert Hyperlink dialog.

<template>
  <ejs-richtexteditor ref="defaultRTE" :placeholder="placeholder" :formatter="formatter" :value="rteValue">
  </ejs-richtexteditor>
</template>

<script setup>
import { provide } from "vue";
import { RichTextEditorComponent as EjsRichtexteditor, Toolbar, Link, Image, HtmlEditor, QuickToolbar, IHtmlFormatterModel, HTMLFormatter } from '@syncfusion/ej2-vue-richtexteditor';
const customHTMLModel = {
  keyConfig: {
    'insert-link': 'ctrl+q', // confite the desired key
  }
}
const rteValue = `<p>The Syncfudion Rich Text Editor, a WYSIWYG (what you see is what you get) editor, is a user interface that allows you to create, edit, and format rich text content. You can try out a demo of this editor here.</p><p><b>Key features:</b></p><ul><li><p>Provides &lt;IFRAME&gt; and &lt;DIV&gt; modes.</p></li><li><p>Bulleted and numbered lists.</p></li><li><p>Handles images, hyperlinks, videos, hyperlinks, uploads, etc.</p></li><li><p>Contains undo/redo manager. </p></li></ul><div style='display: inline-block; width: 60%; vertical-align: top; cursor: auto;'><img alt='Sky with sun' src='https://cdn.syncfusion.com/ej2/richtexteditor-resources/RTE-Overview.png' width='309' style='min-width: 10px; min-height: 10px; width: 309px; height: 174px;' class='e-rte-image e-imginline e-rte-drag-image' height='174' /></div>`,
const placeholder = "Type Something";
const formatter = new HTMLFormatter(customHTMLModel); // to configure custom key
provide('richtexteditor', [Toolbar, Link, Image, HtmlEditor, QuickToolbar]);
</script>

<style>
@import 'https://ej2.syncfusion.com/vue/documentation./node_modules/@syncfusion/ej2/material.css';
</style>
<template>
  <ejs-richtexteditor ref="defaultRTE" :placeholder="placeholder" :formatter="formatter" :value="rteValue">
  </ejs-richtexteditor>
</template>

<script>

import { RichTextEditorComponent, Toolbar, Link, Image, HtmlEditor, QuickToolbar, IHtmlFormatterModel, HTMLFormatter } from '@syncfusion/ej2-vue-richtexteditor';
export default {
  name: "App",
  components: {
    "ejs-richtexteditor": RichTextEditorComponent
  },
  data() {
    var customHTMLModel = {
      keyConfig: {
        'insert-link': 'ctrl+q', // confite the desired key
      }
    }
    return {
      rteValue: `<p>The Syncfudion Rich Text Editor, a WYSIWYG (what you see is what you get) editor, is a user interface that allows you to create, edit, and format rich text content.

      placeholder: "Type Something",
      formatter: new HTMLFormatter(customHTMLModel), // to configure custom key
    }
  },
  provide: {
    richtexteditor: [Toolbar, Link, Image, HtmlEditor, QuickToolbar]
  }
}
</script>

<style>
@import 'https://ej2.syncfusion.com/vue/documentation./node_modules/@syncfusion/ej2/material.css';
</style>

We need to import IHtmlFormatterModel and HTMLFormatter to configure the shortcut key.
