The registered trademark symbol, or more affectionately known as the "R" with the circle around it, essentially says that the image, word or phrase is a registered trademark. If you look at your keyboard, you'll quickly notice that there is nothing that looks remotely close to the registered trademark symbol. On the contrary, you can create the symbol by pressing certain keys at the same time. Once all the keys are pressed and released, the registered trademark symbol, ®, will appear.
Hold down the "Alt" button on your keyboard.
Press "0174" on your keyboard's number pad, without the quotation marks.
Release the "Alt" button. The registered trademark symbol appears.
