Super does the exact same thing as clicking (or just mousing quickly to) "Activities" in the upper-left, which is one of the few UI elements visible on the desktop.

Docked apps also show up in this view, along with a button to show all apps. (Similar workflow as Start -> Program Files.) Keyboard is unnecessary.

It's somehow faster than every hardcore keyboard-based WM I've used (I was a longtime wmi/wmii/i3 user... all of which needed two keystrokes to open the app launcher, e.g. Super+P) and also every mouse-based WM I've used, and also works fantastically from my touchscreen when I'm feeling particularly lazy.
