Keyboard's printed instructions (6)
I believe the answer is:
manual
This clue is a double definition.
'keyboard's' is the first definition.
(thesaurus)
'printed instructions' is the second definition.
(Other definitions for manual that I've seen before include "Done by hand, or a handbook" , "Involving human effort" , "reference book" , "Book; done by hand" , ""How-to" book" .)
