Seize the chance to make a break higher (4,2)

I believe the answer is:

snap up

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

'seize the chance to' is the definition.
I can't tell whether this defines the answer.

'a break higher' is the wordplay.
'a break' becomes 'snap' (I've seen this before).
'higher' becomes 'up'.
'snap'+'up'='SNAP UP'

'make' acts as a link.

Can you help me to learn more?

(Other definitions for snap up that I've seen before include "Quickly accept" , "Grab eagerly and quickly" , "Buy (a rarity) quickly" , "Unhesitatingly take" , "Snatch" .)

I've seen this clue in the Evening Standard.
