I need to substantially change the style of the default lines (i.e. "edges") that connect shapes.
e.g. Is it possible to change the style of the default edges to say a dotted line line without arrow heads?
Failing that, is it possible to "paint" one edge's style onto another edge?
EDIT: Wait, "Current Elements" on the palette on the left of screen seems to more or less do this. It would be preferrable change that actual default and/or be able to paste properties though...
