¡Feliz Navidad!

If you are on a regular computer, with a key pad, you can hold down the Alt button and type the number 164 on the keypad (won't work on the above numbers), then release the Alt button. ñ Tada! Capitalized would be 165 Ñ. You can do this on a laptop buy you need to turn on the keypad and it's a giant PITA.

I can't imagine having a keyboard without ñ or the ability to use accents or umlauts. My Dell desktops and laptops have always come with the right keyboard. Only my Macbook Air has a plain keyboard, so I don't use it except as backup, but I still set it up to be able to write in Spanish. It just takes a little getting used to and I have to consult the keypad guide every now and then.
