Hi there,
It may be a little late to help the original poster, but I hope it helps anyone having the same problem.
The solution is simple: just add Spanish as an additional input language. In Windows go to Control Panel, Regional and Language options, click on the Languages tab, click on Details... and add an Spanish keyboard. I am Mexican and I always use Mexican/Latin American Spanish setting, no matter that my computer doesn't have such keyboard. Some of the keys will change. For instance:
"Ñ" will be where semicolon is
to put a tilde on vocals, strike the key next to letter "p" first, then the vocal
"¿" symbol is the "plus" sign is
"¡" symbol is <shift> "plus" sign
quotation marks are above number 2
for the rest of them you will have to try yourselves. I do.
And the good thing is you can switch between Spanish and English by pressing <alt><shift> or by clicking and selecting from the language bar in the Task bar (if you decide to leave it on, that is)
Hope it helps u all!
¡Ahí nos vemos, amiguitos!
