Launchy indexes the programs in your start menu and can launch your documents, project files, folders, and bookmarks with just a few keystrokes!
You then type in a few keys of the program you are searching for and hit ENTER once it has been found. You can also make Launchy dissappear again by hitting ESCAPE or ALT+SPACE. You can customize which key combination launches Launchy.
Launchy is developed to run on XP, however you can try downloading the gdiplus.dll and unzipping it into your Launchy directory to get it to run with Win2000.
You can extend and customize Launchy with many cool themes and plugins developed by its thriving user community.
Once Launchy has been started, it hides in the background. You bring it forward by holding the ALT key and tapping the SPACE key.
