Keyboard shortcuts can greatly increase productivity once you are fluent with them. This is not an extensive list by any means, there are many more key combinations that you can use to launch apps, minimize and maximize windows, and do all sorts of other functions. This is a list to get you started with the most common ones that I employ often. Start using these with your daily tasks and I bet your mouse will start to feel lonely.
