Adding an item to the clipboard to then place at a different position either in a document or location
When you want to transfer a duplicate of one thing into another area or location, then you'll find it to your advantage to use Copy + Paste.
- Copy: Ctrl + C
- Paste: Ctrl + V
- Copy: ⌘ + C
- Paste: ⌘ + V
If you want to cut something out instead, you can often swap it with X.
