function registerKeyHandlers () {
    let button =  $("#buttonContainer").dxButton("instance");
    button.registerKeyHandler("backspace", function (e) {
        // The argument "e" contains information on the event
    });
    button.registerKeyHandler("space", function (e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxButtonModule, DxButtonComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxButtonComponent) button: DxButtonComponent
    ngAfterViewInit () {
        this.button.instance.registerKeyHandler("backspace", function (e) {
            // The argument "e" contains information on the event
        });
        this.button.instance.registerKeyHandler("space", function (e) {
            // ...
        });
    }
}
@NgModule({
    imports: [
