Life In 19x19

I have been trying to use the EidoGo player as an SGF editor for commenting some games. I can't seem to figure out a way to add variations to a move though Am I missing something obvious ?

While looking at the prior move, you can just click a point on the board, and it will insert that as a variation for the next move. Or do I misunderstand what you mean?

Thanks ! That solved my confusion
