Try holding down your Alt button then hitting 155 (1 then 5 then 5 again) on your keypad over to your right. I hope that's where your keypad is; just don't use the numbers in the row across the top of your keyboard.

There're all kinds of cool things in there! 130 = é; 167 = º; 171 = ½. Experiment; backspace if you want to get rid of something.

It should work in e-mail, too, if you want to practice without coming here. Any time I'm practicing something or doing something I'm not too sure of, I set up an e-mail to myself so that if I accidentally hit Send I won't be mortified that somebody else is reading my foolishness.

And I owe my knowledge of this to tsuwm; thank you again, sir.
