Newbie question I know, but how can I fill with a two-color gradient... or must a gradient be from the fill-color in the current object, to the fill-color of the underlying object? BTW, how do I get the gradient-handle to show in an object (so I can drag where the gradient starts and stops, as well ...

I want to create an effect using opacity, so I have to objects of identical shape exactly on top of each other. Is there a way to select them both and merge them? (As the top one cover the bottom one, I can't "see" the bottom one to select it.)
