What's Ubiquity--User's Perspective

Ubiquity is a Firefox extension and it provides you with a different way to navigate and interact with your computer through the use of keyboard shortcuts and typed commands. Ubiquity let you apply textual commands (called "verbs") to whatever you're looking at on your screen. See here for its formal introduction. You can also view the video below:
