UD Principle #6 - Low Physical Effort
The design minimizes the physical effort required to use by allowing the user to comfortably maintain a neutral body position, minimize repetitive actions and limit heavy operating force and physical effort. We may not first associate physical efforts with using the web. Anyone can easily just sit down and use a mouse, but technology is now integrated and ubiquitous in workplaces. Many people are using their computers for eight or more hours to perform tasks at work. The amount of time we spend on our computers is taxing on our bodies. In fact, people with physical disability have even more difficulty with using the web than normal users do.

A great example of this design principle is using keyboard shortcuts; they reduce the need to move from the keyboard to the mouse for simple tasks. Most browsers such as Chrome, Firefox, and Safari provide keyboard shortcuts to perform tasks such as copy (Ctrl + C) and paste (Ctrl + V). You can design superb interactive experiences by adding appropriate keyboard shortcuts. They will improve the navigation and make websites easier to use for all users.
