What's Star-Tap

I’m looking at Experience the New OneDrive: Fast, Organized, and Personalized - Microsoft Community Hub which references the star-tap experience.   I’ve searched & can’t find anything about it.

“Favorites and File Shortcuts    We’re adding two new ways to manage and find important files. Now, you can easily favorite files in OneDrive using the familiar ‘star-tap’ experience found in Microsoft 365 apps. “

Thanks in advance.
