Publisher review:QuickSilver is a powerful application launcher. It can also replace Spotlight, the search engine built into Apple Mac OS X.
If you want an application hidden on your file system, simply activate Quicksilver with a keystroke, type the application name then hit Return or Enter to launch it.
Quicksilver keeps out of your way when you don't need it, preserving precious screen real estate, but you can access it instantly with a key stroke.
Programmers can extend and customize Quicksilver until it does exactly what you want it to.
Operating system:Mac OS X 10.6 or later
