Window-shop; graze (6)
I believe the answer is:
browse
This clue is a double definition.
'window-shop' is the first definition.
(I've seen this in another clue)
'graze' is the second definition.
(I know that graze can be written as browse)
(Other definitions for browse that I've seen before include "Thumb through" , "Surf (the Internet)" , "Look at various things on the Internet" , "Eat by continually nibbling" , "Examine cursorily" .)
