In an orderly manner (6)
I believe the answer is:
neatly
'in an orderly manner' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for neatly that I've seen before include "In a tidy manner" , "With deftness" , "In a tidy way" , "In tidy fashion" , "Orderly and cleanly" .)
