Copy and paste is just like it sounds. You copy text or graphics and paste them in the same or another document. On your computer, Copy text from the screen and Paste into a text area in your Word Processing program.
Use Ctrl-C to copy the highlighted area, or the whole page, then Ctrl-V to paste.
TIP: Highlighting - To select an area, hold the left mouse button down while moving the mouse. Hold the Shift key down while pressing the left mouse button to extend a selected area. Ctrl + left mouse button may be used when a list of files is offered (add to/remove from list).
