A productivity goodie (and it is an open source application) for Windows user – enter Launchy.
It is an utility that obsoletes your start menu – because it can index any programs, documents, or folders with keystrokes.
How many keystroke it involves to launch Firefox?
Press Alt-Space to activate Launchy panel, type ‘fir’ and it should choose Firefox for you. If it is not? Hit Down-arrow and run it by Enter key. As it stores the running frequency, next time when you type ‘fir’, it should prefer the Firefox shortcut than others.
Try it, it will help you to get to the files or shortcuts you need quickly.
