"Command+C" is a keyboard shortcut commonly used on Apple computers to copy selected text, images, or files. When you press the "Command" key along with the "C" key, the highlighted content is stored in the clipboard, allowing you to paste it elsewhere. This function is part of a series of shortcuts that enhance productivity by reducing the need for mouse clicks. After using "Command+C," you can paste the copied content using "Command+V." This method is widely used in various applications, including text editors, web browsers, and file management systems.
