Gnome Do for Linux allows you to search for many items present on your desktop or the web, and perform useful actions on those items. If you know what you're looking for, do will help you find and act on it faster. Send emails and IMs, play music, search the web, and launch applications too. Do is just as sleek, swift and smart on KDE and other common environments. Post your status to Twitter or Identi.ca, and get notified when your friends post. Instantly search your Google contacts and their contact details. Control playback, browse your music library, or search by artist or album.
