Quicksilver is a launcher utility app for Mac OS X which gives you the ability to perform common, every-day tasks rapidly and without thought. An introduction to Quicksilver's abilities include: accessing applications, documents, contacts, music and much, much more. Browsing your Mac's filesystem elegantly using keywords and 'fuzzy' matching. Managing content through drag and drop, or grabbing selected content directly. Interacting with installed applications through plugins.
