"Ctrl + V" is a keyboard shortcut used to paste text or other content that has been copied or cut to the clipboard. When you select an item and press "Ctrl + C" to copy or "Ctrl + X" to cut, the item is stored temporarily in the clipboard. Pressing "Ctrl + V" allows you to insert that content into a document or application. This shortcut is widely used in various software programs, including word processors like Microsoft Word and web browsers. It helps users quickly transfer information without needing to use the mouse, making tasks more efficient and streamlined.
