    navBar.registerKeyHandler("space", function (e) {

}

TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxNavBarModule, DxNavBarComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxNavBarComponent) navBar: DxNavBarComponent
    ngAfterViewInit () {
        this.navBar.instance.registerKeyHandler("backspace", function (e) {
            // The argument "e" contains information on the event
        });
        this.navBar.instance.registerKeyHandler("space", function (e) {
            // ...
        });
