A Spanish keyboard can be added to your Microsoft or Mac operating system to create the unique symbols and letters used in the Spanish language without having to purchase a new keyboard. Otherwise, a computer user would have to remember the special codes or shortcuts to get the same symbols on the English keyboard. Computer keyboards can be configured to specific languages with a few changes to the operating system's configuration.
