I have been a fan of Gnome-Do for a long time. Mac users have been used to having programs just a few keystrokes away with Quicksilver search, and Windows joined the fun with its newly designed start menu in Vista and 7.

Cardapio can work in two modes: as a panel applet (in which case it is an alternative to Gnome’s application menu applet) or as a stand-alone launcher (in which case it is an alternative to the simplest use-cases of Gnome Do). It has a beautiful gtk-native interface and includes plugins for performing inline searches of Files (via Tracker), Software Center, Google, Wikipedia, and much more!
You can set the shortcut to any combination you like. I have mine set to Super (the key with the windows flag) and Space. I’ll show you how to do this after how to install the program.

sudo add-apt-repository ppa:cardapio-team/unstable
sudo apt-get update
sudo apt-get install cardapio
