Nan,
multiclick twists work in the following way:

you select ridge/edge/vrtex by click in it
program highlights stickers that may be moved by the twist
you click some highlighted sticker
programs checks where it can go and highlights possible destinations
you click the destination sticker for your twists
if more than one twist is possible, and last clicked sticker may go to different places, program highlights them - and go to previous step
if there is only one destination for last clicked sticker, but more than one twist is possible, program highlights stickers that have more than one destination - and go to step 3.
So when you click the edge in ET three times, you say "twist this edge, but keep this sticker in place". There is only one possible twist (180 deg). For 120 deg you should select different destination for the sticker (3C sticker on other cell).

Program doesn’t know the type of the axis - is knows only that it’s not passes through cell center. And I couldn’t find best axis and twist for all situations - so I implemented "stickers chain"-based interface for them.
