How do I tap a tab in tvOS simulator?

I created a sample tvOS app in Xcode and selected "tabbed application".

Now I have a First, Second buttons at the top that looks like the equivilant of a tab bar. The simulator remote says "Press Option to touch". Pressing Option and clicking on the remote does nothing.

How do I change tabs?

Besides using Apple TV Remote, you can also use keyboard → and ← to select different tabs.
