Slickrun
Once in a while you come across an application that makes you excited. Slickrun is one of those.
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.
Best of all it is free. You can download it here.
