Document Editor triggers the keyDown event every time when any key is entered and provides an instance of DocumentEditorKeyDownEventArgs. You can use the isHandled property to override the keyboard shortcut behavior.
The following code shows how to prevent the CTRL + C keyboard shortcut for copying selected content in document editor.
import * as ReactDOM from 'react-dom';
import * as React from 'react';
import { DocumentEditorComponent, DocumentEditorKeyDownEventArgs, SfdtExport, Selection, Editor } from '@syncfusion/ej2-react-documenteditor';
DocumentEditorComponent.Inject(SfdtExport, Selection, Editor);
export class Default extends React.Component<{}, {}> {
public documenteditor: DocumentEditorComponent;
public componentDidMount(): void {
this.documenteditor.keyDown = function (args: DocumentEditorKeyDownEventArgs) {
let keyCode: number = args.event.which || args.event.keyCode;
let isCtrlKey: boolean = (args.event.ctrlKey || args.event.metaKey) ? true : ((keyCode === 17) ? true : false);
//67 is the character code for 'C'
if (isCtrlKey && keyCode === 67) {
//To prevent copy operation set isHandled to true
args.isHandled = true;
}
}
}
render() {
return (
<DocumentEditorComponent
id="container"
ref={scope => {
this.documenteditor = scope;
}}
isReadOnly={false}
enableSelection={true}
enableEditor={true}
height={'330px'}
/>
);
}
}
ReactDOM.render(<Default />, document.getElementById('sample'));import * as ReactDOM from 'react-dom';
import * as React from 'react';
import { DocumentEditorComponent, SfdtExport, Selection, Editor } from '@syncfusion/ej2-react-documenteditor';
DocumentEditorComponent.Inject(SfdtExport, Selection, Editor);
export class Default extends React.Component {
componentDidMount() {
this.documenteditor.keyDown = function (args) {
let keyCode = args.event.which || args.event.keyCode;
let isCtrlKey = (args.event.ctrlKey || args.event.metaKey) ? true : ((keyCode === 17) ? true : false);
//67 is the character code for 'C'
if (isCtrlKey && keyCode === 67) {
//To prevent copy operation set isHandled to true
args.isHandled = true;
}
};
}
render() {
return (<DocumentEditorComponent id="container" ref={scope => {
this.documenteditor = scope;
}} isReadOnly={false} enableSelection={true} enableEditor={true} height={'330px'}/>);
}
}
ReactDOM.render(<Default />, document.getElementById('sample'));Override or define a new keyboard shortcut behavior instead of preventing the keyboard shortcut.
For example, Ctrl + S keyboard shortcut saves the document in SFDT format by default, and there is no behavior for Ctrl + Alt + S. The following code demonstrates how to override the Ctrl + S shortcut to save a document in DOCX format and define Ctrl + Alt + S to save the document in SFDT format.
import * as ReactDOM from 'react-dom';
import * as React from 'react';
import { DocumentEditorComponent, DocumentEditor, SfdtExport, Selection, Editor, DocumentEditorKeyDownEventArgs } from '@syncfusion/ej2-react-documenteditor';

export class Default extends React.Component<{}, {}> {
public documentEditor: DocumentEditorComponent;
public componentDidMount(): void {
this.documentEditor.keyDown = (args: DocumentEditorKeyDownEventArgs) => {
let keyCode: number = args.event.which || args.event.keyCode;
let isCtrlKey: boolean = (args.event.ctrlKey || args.event.metaKey) ? true : ((keyCode === 17) ? true : false);
let isAltKey: boolean = args.event.altKey ? args.event.altKey : ((keyCode === 18) ? true : false);
// 83 is the character code for 'S'
if (isCtrlKey && !isAltKey && keyCode === 83) {
//To prevent default save operation, set the isHandled property to true
args.isHandled = true;
//Download the document in docx format.
this.documentEditor.save('sample', 'Docx');
args.event.preventDefault();
} else if (isCtrlKey && isAltKey && keyCode === 83) {
//Download the document in sfdt format.
this.documentEditor.save('sample', 'Sfdt');
}
}
}
render() {
return (
