Longed to fix the editor! (5)
I believe the answer is:
pined
'longed' is the definition.
('pine' can be a synonym of 'long')
'fix the editor' is the wordplay.
'fix' becomes 'pin' (to pin is to fix in place).
'the editor' becomes 'ed' (abbreviation).
'pin'+'ed'='PINED'
'to' acts as a link.
(Other definitions for pined that I've seen before include "Starved" , "Languished, yearned" , "Longed; wasted (away)" , "Became ill with longing" .)
