Select the required text by holding down mouse button 1 and dragging the cursor over it.
Release mouse button 1.
Point the mouse at the location to which you wish to duplicate the text, and click mouse button 2.
By default, mouse button 2 is the middle mouse button. The text is copied to the new location without removing it from its original location.
(Optional) Repeat step 3 and duplicate the text in other locations.
