Brief, displaying discretion (10)

I believe the answer is:

directions

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

'brief displaying discretion' is the definition.
I can't tell whether this defines the answer.

'displaying discretion' is the wordplay.
'displaying' indicates anagramming the letters (the anagrammed letters display the answer).
'discretion' is an anagram of 'DIRECTIONS'.

Can you help me to learn more?

(Other definitions for directions that I've seen before include "News reveals four" , "North, south, east and west?" .)

I've seen this clue in The Everyman puzzle in The Observer.
