I know that on a typewriter one could hit lower case c, backspace and then hit / to make the cent symbol, and one would often move the platen back a half notch to make the degree symbol with a lower case o. But to be honest, if it wasn't for getting back to my home directory I would hardly ever use the ~ symbol. That keyspace (literally, key space) could have been used for the degree symbol. With 100+ key keyboards, that have many redundant keys (think number pad) and symbols that are seldom used, or only used in programming because they were on the keyboard anyway, what symbols would you replace?"
