The Navigator add-in adds NavigateToNextTab and NavigateToPreviousTab commands to navigate tabs using keyboard. These commands stop when they reach the first or the last tab. This week Chee-Hung Loh posted to the Tabs Studio mail list code for NavigateToNextTab go to first tab if the selected tab is the last tab and NavigateToPreviousTab go to the last tab if the selected tab is the first tab. And then added an option to select between the default and new behavior. To access navigator options go to Add-in Manager, select Navigator and press Configure:

I’ve also added the NavigateToLastTab command for symmetry with NavigateToTab1:
