Keyboard shortcuts are keys or a combination of keys you can press on your keyboard to perform a variety of tasks. Using keyboard shortcuts is often faster than using a mouse because you can keep both hands on the keyboard. Keyboard shortcuts are also universal, which means you can use many of the same shortcuts in a variety of applications. For example, you can use the shortcuts to copy and paste text in a word processor and in a web browser.
