"Ctrl + C" is a keyboard shortcut commonly used in computer applications to copy selected text or objects. When you press these keys simultaneously, the highlighted content is stored in the clipboard, allowing you to paste it elsewhere using another shortcut, "Ctrl + V." This function is available in most operating systems, including Windows, macOS, and Linux. This shortcut is particularly useful for quickly duplicating information without the need to retype it. It enhances productivity by streamlining tasks such as writing documents, coding, or managing files. Understanding how to use "Ctrl + C" can significantly improve your efficiency when working on a computer.
