Typing in Spanish/Escribiendo en Espanol

I'm still trying to figure out how to type in Spanish. You know, the Spanish language uses a different alphabet. Yep, a lot of the letters are the same as in the English langage, a couple are similar. The problem is, my keyboard does not have Spanish characters. I've looked up how to type them but for some reason it isn't working in "blogger"... I'll figure something out.
