In the Finder, `Command-I` will "Get Info" for a given window. You know this.
But also try `Option-Command-I` to "Get Info" for the currently selected Finder item(s).
So then, you can click around, and do stuff, and it just recycles that one window. And it's crazy useful for a whole bunch of things.
Like, select nothing in a window, and it'll just "Get Info" for that window.
It's gold.
