I need to automatically change between 2 tabs in perspective.  
Can someone give me some ideas on how to do this.

Thanks

Binding `props.currentTabIndex` to an expression should work:

```python
floor(getSecond(now())/30)

```

Can you use the same expression for 4 tabs?

</div>

```python
floor(
  (now(1000) / 3000) // 3000 ms on each tab
  % len({this.props.tabs}) // modulo operator
)

```

This will make editing the tab container almost impossible. To fix that, right-click on the binding and disable during the edit. You would need to remember to re-enable when you're finished editing.
