wow, i was not aware of this! this also works to trigger menu items that don't have assigned keyboard shortcuts. I use Macs since Mac OS 9 and somehow I never discovered this.

on Big Sur this also hovers an arrow next to the menu item, this is what it looks like:

Arrow exists on Catalina as well.

I'm on Mojave, where it also exists. I'm pretty sure that I remember it being around since at least the days of Tiger (10.4), and that the only reason that I can't vouch for it earlier is that Tiger is when I entered the OS X ecosystem.

Definitely present in Snow Leopard (the last good version).
