Copy paste without keyboard

There are two clipboards. Did you know?

In Linux you have the X-Windows clipboard in addition to the Ctrl+C-Ctrl+V clipboard. You have two clipboards!

That X-clipboard works like this: select text with the mouse. That is the copy action. And then go to where you want to paste the text and paste with the middle mouse button.

If you have done Ctrl+C-Ctrl+V very often in your life, it takes some getting used to to suddenly do it (also) differently.
