• If you are using a desktop computer, entering the following codes on your alpha-numeric keypad (the number pad on the far right of the keyboard) will produce the indicated characters.
• If you are using a laptop computer, you should know that the alpha-numeric keypad is embedded in the letter keyboard.  You will need to active the numeric keypad by typing the correct code (indicated in the user's manual which came with your laptop--different brands use different codes), then type "Alt" and the number (note that the letter keys which have numbers embedded in them have these numbers printed on the side of the key).  You will then need to deactivate the numeric keypad to return to the letter keyboard to continue typing.
