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

'a sign of anxiety' is the definition.
'edginess' can be an answer for 'anxiety' (edginess is a kind of anxiety). I am not certain of the 'a sign of' bit.

'digs seen in disarray' is the wordplay.
'in disarray' is an anagram indicator.
'digs'+'seen'='digsseen'
'digsseen' anagrammed gives 'EDGINESS'.

Can you help me to learn more?

(Other definitions for edginess that I've seen before include "Tenseness, nervousness" , "Feeling of anxiety, disquietude" , "State of nervous tension" .)

I've seen this clue in The Globe and Mail.
