If you are using a keyboard without a number pad, and using the Windoze O/S, you can use a built-in utility called "Character Map"

It is so useful, I keep a shortcut for it on my desktop and/or task bar.

Typically, it is under the Start > Programs > Accessories > System Tools

Using this, one can select any character, hit "select" and then "copy" to copy and paste it into any document.

Yes, I've used the extended ASCII character set via the number pad for many years (since DOS) but the "Character May" utility is far more comprehensive.

Btw, the ° and ± symbols (alt+176, alt+177) are extremely useful and most technical folks have then memorized. Likewise for the ä, ë, ï, ö, ü, and ß characters for those who regularly need to type in German.

If you scroll through the "Character Map" utility, you'll see lats of characters useful for typing in other languages. It also gives the extended ASCII code. if one is available for that character (like ã and ñ).
