afoot

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

'a pair of spectacles wrapped in pink paper in train' is the definition.
I can't judge whether this definition defines the answer.

'a pair of spectacles wrapped in pink paper' is the wordplay.
'pair of spectacles' becomes 'OO' (OO looks like spectacles).
'wrapped in' indicates putting letters inside.
'pink paper' becomes 'ft' (Financial Times).
'oo' put inside 'ft' is 'foot'.
'a'+'foot'='AFOOT'

Can you help me to learn more?

(Other definitions for afoot that I've seen before include "Under way (like hunted game?)" , "Brewing" , "Progressing, in operation - like Sherlock Holmes's game" , "in the air" , "Happening" .)
