There's always Ctrl+Insert for copy and Shift+Insert for paste. I know that there's some laptops lacking an insert key, which is terrible, but for keyboard with an insert key the Ctrl/Shift + Insert combos are useful at times.
Especially because one does not have to push three keys with the same hand, which is not nice to tendons. I think I did that for a while time ago, then forgot about it. Thanks.
