Quicksilver is a unified, extensible interface for working with applications, contacts, music, and other data. Quicksilver will create a catalog of applications and some frequently used folders and documents. Activate it, and you can search for and open anything in its catalog instantly. The search is adaptive, so it will recognize which items you are searching for based on previous experience.
Among other things, files can be emailed, copied, compressed. Text can be modified, transmitted between programs, or searched for on the web. Quicksilver can be given the ability to understand the data inside of files, allowing you to work with data in new, faster ways. Frequently used commands can be bound to triggers, giving you the ability to execute them immediately by hitting a hot key or using the mouse on a corner or edge of the screen.
