It’s not really advertised or intuitive in any way, so that doesn’t surprise me. In fact, I have no recollection of how I came upon this feature. Maybe I discovered it in a fever dream, maybe it was on a lifehacker.com listicle. I’m not even sure it’s supposed to be a feature, for all we know it could be an odd quirk, some legacy code in explorer.exe. The inner machinations of Windows are an enigma.
