In a way, nothing for me to make a gesture about (7)

I believe the answer is:

somehow

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

'in a way' is the definition.
(I've seen this before)

'nothing for me to make a gesture about' is the wordplay.
'nothing' becomes 'O' (O resembles 0).
'for' means one lot of letters go next to another.
'to make a gesture' becomes 'show' (I can't justify this - if you can you should believe this answer much more).
'about' is an insertion indicator.
'o'+'me'='ome'
'ome' inserted inside 'show' is 'SOMEHOW'.

Can you help me to learn more?

(Other definitions for somehow that I've seen before include "For some unspecified reason" , "In an unspecified way" , "By unspecified means" , "For an unknown reason; so who, me? (anag.)" , "In an unspecified manner" .)

I've seen this clue in the Evening Standard.
