To navigate between toolbar items using the Tab key, disable allowKeyboardNavigation in Diagram Toolbar instances. Call dxToolbar.defaultOptions() as follows:

jQuery
index.js
DevExpress.ui.dxToolbar.defaultOptions({
    options: {
        onInitialized(e) {
            if ($(e.element).closest('.dx-diagram').length) {
                e.component.option('allowKeyboardNavigation', false);
            }
        }
    }
})
Angular
app.component.ts
import dxToolbar from "devextreme/ui/toolbar";
import { type DxToolbarTypes } from "devextreme-angular/ui/toolbar";
// ...
export class AppComponent {
    constructor() {
        dxToolbar.defaultOptions({
            options: {
                onInitialized(e: DxToolbarTypes.InitializedEvent) {
                    if (e.element?.closest('.dx-diagram')) {
                        e.component?.option('allowKeyboardNavigation', false);
                    }
                }
            }
        })
    }
}
Vue
App.vue
<script setup lang="ts">
import dxToolbar from "devextreme/ui/toolbar";
import { type DxToolbarTypes } from "devextreme-vue/toolbar";

dxToolbar.defaultOptions({
    options: {
        onInitialized(e: DxToolbarTypes.InitializedEvent) {
            if (e.element?.closest('.dx-diagram')) {
                e.component?.option('allowKeyboardNavigation', false);
            }
        }
    }
});
</script>
React
App.tsx
import dxToolbar from "devextreme/ui/toolbar";
import { type ToolbarTypes } from "devextreme-react/toolbar";

dxToolbar.defaultOptions({
    options: {
        onInitialized(e: ToolbarTypes.InitializedEvent) {
            if (e.element?.closest('.dx-diagram')) {
                e.component?.option('allowKeyboardNavigation', false);
            }
        }
    }
});

Replace .dx-diagram with a component ID or class to modify keyboard navigation behavior in a specific component only.

IMPORTANT
If you disable allowKeyboardNavigation, the DevExtreme Toolbar no longer follows the W3C ARIA APG Toolbar Pattern. Your application will be less accessible to users who rely on keyboard navigation.
