I believe the answer is:

glance

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

'look' is the definition.
(I know that glance is a type of look)

I can't explain the remainder of the clue.

(Other definitions for glance that I've seen before include "Butcher" , "Batsman's stroke" , "Swift look" , "A dart of the eye" , "Stroke - gander" .)

I've seen this clue in The Globe and Mail.
