I'm not sure what internet browser you are using, but with Google you'll find three bars in the upper right hand corner of the screen. Now keep that in mind.

Pick out the passage that you want to cut and paste, set your cursor at the beginning of the passage and WHILE HOLDING DOWN THE LEFT BUTTON ON YOUR MOUSE move your cursor over the passage.

Then go to the three bars in the upper corner of the screen and click it. There will be a drop down menu and just click copy.

Now go to where you want to paste the passage and mark it with your cursor by clicking. Then go back to the three bars, click it and from the drop down menu, click paste.

That's all there is to it.
