This is really helpful to know - it's one of my biggest bugaboos about using Finder & navigating the Mac GUI.
On the other hand, I suspect this kind of obscure key-based shortcut is a big part of why Macs don't feel intuitive to a lot of users. How could I have known this shortcut exists? It's not broadcast anywhere obvious. My options for finding all these obscure shortcuts aren't great. I could scroll through a submenu in the Settings pane, hoping to find something that looks like it says the thing I'm trying to do (and then that I can figure out what keys it means, since Apple key symbology is VERY arcane). I could stumble across a mention of the shortcut in a forum like this. Or I could Google in the hope of finding something - though that assumes I believe it's doable in the first place, which I didn't in this particular case.
It would also help if Apple chose easier / more intuitive keyboard shortcuts. A "shortcut" which both is the only way to do something, and also requires pressing a minimum of four seemingly-random keys, is not a shortcut at all - it's a mental load on the user that they just have to hold in their heads forever.
