<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">keyboard operator</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for typist that I've seen before include "One using keyboard" , "Pre-computer office worker" , "Forerunner of the word processor operator" , "Skilled keyboarder" , "One uses an old-fashioned keyboard" .)
