Synapse is a desktop utility that adds speed and convenience to finding files and launching applications. It does not eliminate the Linux distro’s menu, favorites bar or panel icons. Instead, it cuts down on how often you resort to using them. A semantic-based tool that makes use of the Zeitgeist engine, Synapse is a graphical launcher that pops up when you call it with the Control-Space key combination. Type what you want to do, and use the arrow and enter keys to navigate through a list matching your query.
