Sort to use a keyboard? (4)
I believe the answer is:
type
I believe this is a double definition.
'sort' is the first definition.
(type is a kind of sort)
'use a keyboard?' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for type that I've seen before include "Use keys" , "Class or group of a particular class" , "Figure" , "Print form" , "Sort - pattern - print" .)
