Synapse is a new application launcher which does some amazing things.
Uptill now, like many I am a GNOME Do user, however Synapse has changed that. GNOME Do is an amazing application no doubt - but Synapse takes it further with its tight Zeitgeist integration. The Zeitgeist integration means that it not only launches applications - but also allows you to access your system files using the Zeitgeist log.
By default the shortcut to launch Synapse is CTRL+Space (You can change it). After launching, just like in GNOME Do, you have to type in the name of the application. Because of the Zeitgeist integration, you can also type in name of previously opened files and press ENTER to open it with the default application or TAB to choose a different one.
