¹⁰For example, the Baudot code 11101 meant either “Q” or “1” depending on whether the last shift character was “letters” or “figures,” respectively. The code 01010 meant either “R” or “4”. The code 00001 meant either “T” or a “5”. This overloading of codes is equivalent to using the “shift” key on a computer keyboard to switch between numbers and symbols (e.g. “5” versus “%”, or “8” versus “*”). The use of a “shift” key on a keyboard allows single keys on the keyboard to represent multiple characters.
