So here are the most important shortcuts you can learn:
Name | Windows | Mac | Result |
Copy | Ctrl+C | Cmd+C | Copies selected item |
Paste | Ctrl+V | Cmd+V | Pastes the last item you copied/cut |
Cut | Ctrl+X | Cmd+X | Deletes selected item and holds to paste elsewhere |
Select All | Ctrl+A | Cmd+A | Highlights all the items on the page so you can quickly copy/cut or delete |
