Transported via Gate Four? (9)

I believe the answer is:

entranced

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

'transported' is the definition.
(I've seen this before)

'gate four?' is the wordplay.
'gate' becomes 'entrance' (I've seen this before).
'four?' becomes 'd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'entrance'+'d'='ENTRANCED'

'via' is the link.

Can you help me to learn more?

(Other definitions for entranced that I've seen before include "Transported" , "Filled with wonder" , ""Spellbound"?" , "Cast a spell" , "Delighted" .)

I've seen this clue in The Telegraph.
