Keyboard Navigation
The keyboard navigation of the TabStrip is always available.
When focus reaches the tab list, use the Arrow Left and Arrow Right keys to move between horizontal tabs. Use the Arrow Up and Arrow Down keys for vertical tabs. The focused tab is activated automatically. You can also activate the focused tab with Enter or Space.
To navigate a Grid inside the active tab, enable the Grid's keyboard navigation with the Navigatable(true) HtmlHelper option. For the Grid TagHelper, set navigatable="true". For details, see the Grid keyboard navigation and Grid hidden-container documentation. Resizing a Grid after its tab becomes visible can correct layout issues, but it does not enable keyboard navigation or control screen-reader announcements.
For a complete example, refer to the demo on keyboard navigation of the TabStrip.
