Simplify the following text for a Grade 6 native English-speaking person.
Original: The telegraph operators soon learned that they could translate the clicks directly into dots and dashes , and write these down by hand , thus making it unnecessary to use a paper tape . When Morse code was adapted to radio communication , the dots and dashes were sent as short and long pulses .
