I believe the answer is:

self-control

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

'restraint' is the definition.
(thesaurus)

'often scroll threads' is the wordplay.
'often scroll' anagrams to 'SELF-CONTROL'.
But, I'm unsure how this is indicated.

'showing' acts as a link.

Can you help me to learn more?

(Other definitions for self-control that I've seen before include "Willpower" , "Composure" , "Entice" .)

I've seen this clue in the Sydney Morning Herald.
