SlickRun
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.
Please note, SlickRun is not a “hotkey” program. If you want a program that lets you press some wacky keyboard shortcut (say, Shift + Win + 1) to run to something, you’ll want to find a different utility. SlickRun is designed to be far more intuitive than “hotkey” programs– You shouldn’t have to keep an awkward mental list of hotkeys for launching your favorite programs. Instead, just type whatever’s most natural for you to remember; with auto-completion, you’ll rarely type more than 2 or 3 characters anyway.Studies have shown that user-defined imperative words are much easier to recall than arbitrary characters like keystrokes.
