Launchy is a free utility for launching applications quickly.
Launchy automatically loads when you start your system and waits for the user to invoke it by pressing Alt + Space or another user-defined hotkey. The user starts typing the name of the program or file they want to launch. Launchy automatically scans its program list for the most accurate match to what the user is typing. When the desired program is found, the user presses enter and the program starts.
Launchy also lets you add directories and file formats to a directory for indexing. This makes it suitable for running almost anything on a computer, including the Internet, music, videos and games. Launchy can also search Google, Wikipedia, MSN, and Yahoo, showing results in your default browser. It also launches bookmarks, if required. Launchy supports plugins that can be added for greater flexibility.
