The first step for copying and pasting on a computer is to select the desired files or text, and then right-click on the selected object, and select Copy. To paste, right-click in the desired area where you wish to paste the text, and select Paste.

Alternatively, use keyboard shortcuts to copy and paste. For Windows or Linux operating systems, after selecting the object, use Ctrl+C to copy and Ctrl+V to paste. Mac operating system users use Command+C to copy and Command+V to paste.

To select text, either drag the mouse across it, or place the cursor at its beginning, hold the Shift key, and use the arrow keys to reach the end of the selection.
