ñ    On my Mac, you hold down the option button and then hit n.  then without touching anything else, just hit n again.  the first action puts the squiggle over the n and the second action does the n.  I am sure its something similar for the other little marks.  Probably a PC has a similar action.
Tengo doce gallinas y un canario. Tal vez después me divorcio puedo conseguir un gato o un perro.  (I cheated!  I used an online translator!  I do speak a little Spanish, less French, and a few words of Creole.)
The above means I have 12 chickens and 1 canary.  Maybe when I get divorced I can have a cat or a dog.
