Pantheon keyboard shortcut overview/cheatsheet

So in Ubuntu you have this thing where you hold the Super key, after a while this keyboard shortcut overview appears (https://wiki.ubuntu.com/Xubuntu/Roadmap/Specifications/Quantal/KeyboardShortcutsOverlay?action=AttachFile&do=get&target=shortcut-hints-overlay-unity.png). This is like one of the most convenient inventions since slices bread to me. I think a lot of people found this very useful. Keyboard shortcuts are empowering, and it's easy to stumble upon this view, because most popular desktop environments work with the Super key for management, and if press Super and you are in doubt ... this is exactly what you need, so the choice of key and the delay are quite good I think. So I suggest adopting both for elementaryOS as well, but just replacing the shortcut keys with those for Pantheon.
