Maybe I'm to skip (4)
I believe the answer is:
omit
'skip' is the definition.
(I know that skip is a more specific form of the action omit)
'maybe i'm to' is the wordplay.
'maybe' is an anagram indicator.
'im'+'to'='imto'
'imto' anagrammed gives 'OMIT'.
(Other definitions for omit that I've seen before include "Leave out or overlook" , "Exclude; veto" , "Leave out, do not include (4)" , "Fail to mention" , "Disregard" .)
