What may help you write CV on a PC? (5,3)
I believe the answer is:
shift key
'pc?' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for shift key that I've seen before include "it produces capital" , "Typewriter feature, used to achieve capital letters" , "Press it to type capitals" , "Use it to move from lower-case to upper-case letters" , "means of capital production" .)
