One of several hands, each forward (8,5)

I believe the answer is:

straight ahead

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

'one of several hands' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'each forward' is the wordplay.
'each' becomes 'straight' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'forward' becomes 'ahead' (synonyms).
'straight'+'ahead'='STRAIGHT AHEAD'

Can you help me to learn more?
