<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">use a keyboard</span>' is the definition.<br/ ><span class="explanation-format__explanation">(typing with a keyboard)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for type that I've seen before include "Class, kind or printed characters" , "Mark" , "Category, sort" , "key" , "of a certain kind" .)
