Shortcut keys are specific combinations of keyboard keys that perform tasks quickly without the need to navigate through menus or use a mouse. They are designed to save time and increase productivity by allowing users to execute commands instantly. For example, instead of clicking multiple times to copy and paste text, you can use shortcut keys to do it in seconds.
