In the editor? That's simple, just highlight the words with your mouse then right-click and hit "copy". Do the same when pasting, only click "paste" on the popup menu.
I don't believe Ctrl-C and Ctrl-V works in the editor. At least it doesn't for me.
Non nobis, Domine, non nobis sed domini tuo da gloriam!
