Get closer to animal park with motorway direction (4,2)

I believe the answer is:

zoom in

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

'get closer' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'animal park with motorway direction' is the wordplay.
'animal park' becomes 'zoo' (I've seen this in another clue).
'with' says to put letters next to each other.
'motorway' becomes 'MI' (resembles M1, English motorway).
'direction' becomes 'N' (N is an example).
'zoo'+'mi'+'n'='ZOOM IN'

'to' is the link.

Can you help me to learn more?

(Another definition for zoom in that I've seen is " Focus more closely".)

I've seen this clue in the Sydney Morning Herald.
