The keyboard shortcut "Control + V" is commonly used to paste text or other content that has been copied or cut to the clipboard. When you select text or an image and press "Control + C" to copy or "Control + X" to cut, the item is stored temporarily in the clipboard. "Control + V" allows you to insert that content into a document or application. This shortcut is widely supported across various operating systems, including Windows and Linux, as well as many software applications like Microsoft Word and Google Docs. It provides a quick and efficient way to transfer information without needing to use a mouse.
