Using CTRL+C/V requires an unholy synchronization of mouse and keyboard. But unix-style middle-click paste is entirely mouse-controlled and very elegant. Of course, if you are inside a text file, you can use vim keyboard tricks that are even faster because you don't need to select the text.

You can select text with the keyboard by holding down the shift-key, and use the cursor-keys or use ctrl to efficiently jump by word-boundaries.

No mouse required.
