I'm a little stuck... Click here to teach me more about this clue!

'draw attention to' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for highlight that I've seen before include "Best part (of hair or text?)" , "Most memorable part of event" , "Draw attention to - streak in hair" , "Climax" , "the moon?" .)

I've seen this clue in The Sun.
