If you copy a text, it does not change the text's position. You can then use the paste command to duplicate the same text into another position. First, highlight the text you want to move. The use the edit menu at the top of your screen and scroll down to copy. Or you can use the keyboard commands( usually "command, "C"). Go to the place in your document where you want the copied text to be placed. Make an insertion point by clicking your mouse in that space. Then go up to the Edit menu and scroll down to "paste" ( or use the keyboard command, usually command, "V"). The text in now duplicated in the new position.
