left, right and together arrows

[Ingvild Roald]

For years we in Norway have been using the 'together' arrow when the two 
hands are moving as a unit, even if they are not touching. This will be when 
the hands are in certain classifier shapes, and what is 'really' moving is 
the thing that the hand holds between them. Just general 'paralell' is not 
enough for our use of the 'both' arrow (sorry Stefan, I know I have written 
some signs violating this rule, as you have pointed out).

Personally, and with at least some deaf Norwegian signers behind me, I feel 
that the 'togheter' arrow should be used (prioritized list)
1) when the two hands are painting the same route, contact or no contact
2) when the two hands are moving in contact, even if the routes do not 
overlap
3) when the two hands are moving as a unit, as in some classifier signs, 
even if they are not touching
4) when the sign would otherwise be hard to read because of crowding of 
symbols.
