Sort to use a keyboard, maybe (4)
I believe the answer is:
type
I believe this clue is a double definition.
'sort' is the first definition.
(I know that type is a type of sort)
'use a keyboard maybe' is the second definition.
(I've seen this in another clue)
'to' acts as a link.
(Other definitions for type that I've seen before include "Character" , "Kind - press keys" , "Kind - kind of writing" , "Print - classification" , "Courier for example" .)
