PC shortcut code (5)
I believe the answer is:
macro
'pc shortcut code' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for macro that I've seen before include "Computer instruction" , "Prefix meaning large or large-scale" , "Computer routine; lens" , "Series of actions done with one instruction (computing)" , "Long (prefix)" .)
