Cool. This isn't what I was referring to, though. 

You are right that standard US keyboards do not have an AltGr key (I've
never seen such a keyboard in the US, only in Europe and possibly in
Canada). On DOS for many years (and I believe this carries through with
Windows) on a US keyboard, you could hold the right Alt key down and
type in the decimal value of the ASCII code on the numeric keypad for
whatever character you wished. I don't know if this was/is possible with
a non-US keyboard.

The AltGr key does seem much more handy for entering unkeyed characters.
