If you want to replicate a word or even a long piece of text, you don't need to type it out all again in a separate place as you have been until now.

Go to the beginning of the word or text you want to copy or replicate and hold down the left mouse button. Next, drag your cursor over all the part you want to replicate. You'll see that it is now all highlighted in blue. Release the left mouse button.

Hover over the highlighted blue and click the right mouse button, a field of options should appear. Select copy with the left mouse button.

Go to the place you want to replicate the text and press the right mouse button. A field of options will appear. Select paste.

And voilà, you have replicated the text in another place without having to type it out by hand.

This also works with numbers.

Please note, this only works on PCs, I have no idea if this is possible with macs.
