SlickRun is a free floating command line utility for Windows. SlickRun gives you almost instant access to any program or website. SlickRun allows you to create command aliases (known as MagicWords), so C:\Program Files\Outlook Express\msimn.exe becomes MAIL.
Enter a web URL into SlickRun and it will launch your browser and navigate to the specified address. Run multiple programs in a few keystrokes, jot a note, look up a definition… SlickRun is the most natural way to interact with your computer.
I have been using SlickRun since years now and I find this utility very helpful. Saves me efforts to use the mouse and open the programs. It has become a mandatory software for my machine. Each application I install the next step I do is create a MagicWord for it.
