An easy way to copy and paste text is to highlight the text you want to copy (you “highlight” the text by holding down the left side of the mouse with your index finger and drag the mouse over the text you wish to copy). Once the text is highlighted, hold the CTRL key down and press the letter “C” on your keyboard. Left click where you want to paste the text. Hold down the CTRL key and press the letter “V” on your keyboard to paste the text.
Give it a try by copying an pasting this text into a Word document.
