Shortcut to hide the desktop icons in GNOME 3

I wrote a small script, which changes this option:

#!/bin/sh
if $(gsettings get org.gnome.desktop.background show-desktop-icons);
then new="false";
else new="true";
fi
gsettings set org.gnome.desktop.background show-desktop-icons $new

You can save the script /somewhere/as/somewaht.sh (with permission to execute) and then add in your keyboardsettings an entry: Keyboardsettings
