How to set a selection to loop continuously

I’m using n-Track Studio Suite 9.1.6.5825 on Windows 10.

I’m sorry for this overly simple question, but how do you make a selection of a part of an audio track and then set that selection to loop continuously? I know there is a very simple way to do it.

Thanks!

Nevermind folks. I figured it out. In the transport, the icon with the two arrows sets the selection to loop.
