Enso (http://www.humanized.com/) is a program launcher that lets you accomplish many different tasks without having to move away from the current application. For instance, while composing an article you can invoke a Google search on a selected word or do a simple computation without interrupting the current workflow. Once installed on your system, Enso works in the background and you can invoke it anytime by pressing the ‘CapsLock' key. To accomplish a specific task, invoke Enso and type in the command relevant to it. For instance, while composing an article on Word, if you need to do a simple calculation, (say, 123*453) just type in the formula (like this: ‘123*453'), select it, invoke Enso and enter the command ‘calculate'.
