How does the use of keyboard shortcuts improve efficiency?

The use of keyboard shortcuts significantly enhances efficiency by enabling quicker access to functions without the need to move the hand away from the keyboard to the mouse. This saves time and allows users to maintain their flow of work, as they can execute commands or navigate through applications rapidly. For example, shortcuts like Ctrl+C for copy and Ctrl+V for paste allow for instant action compared to the longer process of using a mouse to access these functions through menus. Ultimately, the reduction in movement required enhances productivity and keeps the user more focused on their tasks.
