Holding Super Key doesn't show Unity shortcuts

As the title states, when I hold the Super key Unity shortcuts list doesn't appear.

I'm on Ubuntu 12.04 (fresh install). I can see the dock that shows up with numbers on icons to launch applications. Help.

What's your screen's resolution? The keyboard shortcut list is not displayed on small monitors.

Also, make sure it is configured to show the shortcuts running this at terminal:

gconftool-2 --set --type=bool /apps/compiz-1/plugins/unityshell/screen0/options/shortcut_overlay TRUE 

In Ubuntu 12.10, this would be:

gconftool-2 --set --type=bool /org/compiz/profiles/unity/plugins/unityshell/shortcut_overlay TRUE
