Clemorte is a key that allows you to type something but
which does not move the typing head or the carriage (the key is "dead,"
hence the "morte" from the Latin word for dead). The result is that an
accent is typed, and the letter to be accentuated is typed on top. ie:
^a would give you a circonflex a (É). CLEMORTE.PRG does the same thing.
When you type one of the accents on your keyboard, it waits for the next
typed character and accentuates it if possible. If is not possible, it
types both characters side to side.
