Moving while I cannot move I am hemmed in

I think it could be either:

Which length description are you looking for?:

2,6

inaction

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

'i am hemmed in' is the definition.
I can't judge whether this definition defines the answer.

'moving while i cannot move' is the wordplay.
'moving while' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'move' indicates anagramming the letters.
'i'+'cannot'='icannot'
'icannot' anagrammed gives 'naction'.
'i'+'naction'='INACTION'

Can you help me to learn more?

(Other definitions for inaction that I've seen before include "Ionic tan (anag.)" , "Idleness - fighting" , "Lack of movement or endeavour" , "Idleness of nicotian sort" , "Immobility" .)

I've seen this clue in the Evening Standard.
