How do you make a tilde over the letter you?

There are number codes to make tildes. The number codes are different for each letter. In Windows, you hold down Alt while you type the appropriate number code for that letter. Capital letters and lower case letters require different number codes.

Capital A with a tilde is Alt + 0195

Capital N with a tilde is Alt + 0209

Capital O with a tilde is Alt + 0213

lowercase a with a tilde is Alt + 0227

lowercase n with a tilde is Alt + 0241

lowercase o with a tilde is Alt + 0245

Don't use the numbers along the top row of your keyboard. Use the numeral keypad on the side of your keyboard. Turn Num Lock ON.

There is a different way to do this in Mac, and yet another way to do it in HTML.
