Right now this feature to disable isn't in Ubuntu yet.
You can set it by command line for now till the feature is available
gconftool --set "/apps/compiz-1/plugins/unityshell/screen0/options/shortcut_overlay" --type bool false
In case you get gconftool not found, then you can first install the package gconf2 either from Software center or command line
sudo apt-get install gconf2

In my case it shows installed as I have already installed it
