OH PLEASE NO! The Return/Enter key is nice and big and my pinkie is
already on it when I've entered the last line, so it only takes a
microsecond or two more to hit it again to send the command to the
interpreter. Any other solution would probably require a control key
plus some other key (since all single keys present on every keyboard
are already taken).
