The keyboard shortcut "Command + X" is commonly used on Apple computers to cut selected text or items. When you use this command, the highlighted content is removed from its original location and placed in the clipboard, allowing you to paste it elsewhere using "Command + V." This function is particularly useful for editing documents or organizing files, as it enables users to quickly move information without needing to delete and then copy it separately. "Command + X" is part of a set of shortcuts that enhance productivity and streamline tasks on macOS and various applications.
