Read electronically (4)
I believe the answer is:
scan
'read electronically' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for scan that I've seen before include "make a detailed copy of" , "Analyse a piece of verse for metre" , "Scrutinise; glance over" , "Conform to a metrical pattern" , "Look over cursorily" .)
