Man spared wrong sign in text (9)

I believe the answer is:

ampersand

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

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

'man spared wrong' is the wordplay.
'wrong' indicates an anagram.
'man'+'spared'='manspared'
'manspared' is an anagram of 'AMPERSAND'.

Can you help me to learn more?

(Other definitions for ampersand that I've seen before include "Pens drama using &" , "Union character" , "that is seen at the keyboard" , "Man spared (anag.)" , "character (sharing with 7)" .)

I've seen this clue in The Telegraph.
