To copy just place your curser right at the beginning or at the very end of some text, then press the left mouse button and drag it directly across the line(s) of text. It will highlight blue.

Then without touching anything else, put the curser right on the blue highlight and RIGHT click. A drop down menu shows up.

In that list, choose "Copy". It is now on Window's clip board. (the clip board can handle only one copy at a time)

Next, in a fresh text window or even in Word, RIGHT click again and the menu pops up again and now choose "Paste" and Boom! The copied text is now magically there!

Tah Dah!
