You may often need special characters that are not on your keyboard. To create these, you use codes.
There are two systems: Code and Entity. Entity is easier to use. Just remember that you place an ampersand first, the abbreviation for the character (such as "amp" for ampersand), and then a semicolon to close. For example, to produce an ampersand (&), type & in your HTML and it will appear as & in your browser.
Note: You can also enter characters via the numeric keypad into any Windows program. See the instructions and table at the end of this document.
