Im a newbie with omnigraffle and I often find it difficult to select certain parts of a group (say a subgroup) and drag it to a place where I wanna place it. As in like, I've a chart stencil in which the legend display is a subgroup. I want to select that particular legend part and place somewhere though still residing in the group. How do I select the subgroup??
What am I missing can anyone help me??
