The keyboard shortcut overlay is controlled by an option in the compiz unity plugin.
In the experimental tab of ccsm you can untick the option shown.

untick the option shown in the path /apps/compiz-1/plugins/unityshell/screen0/options/shortcut_overlay
For those like me that prefer the command line:
Ubuntu 12.10+:
(Tested up to 16.04)
dconf write /org/compiz/profiles/unity/plugins/unityshell/shortcut-overlay false
Ubuntu 12.04 and below:
sudo apt-get install gconf-editor
gconftool-2 --set /apps/compiz-1/plugins/unityshell/screen0/options/shortcut_overlay --type bool false
For Ubuntu 12.10:

Now you have to look at the second option called Shortcuts hints overlay
Now click at the box to turn this feature off, so this remains as this:
