Select Omnigraffle control points hidden underneath selection handles

Question

I have a custom shape in OmniGraffle 6. I don't know how to select the control points (little blue diamonds) because they are hidden underneath the object selection handles (little white squares). How can I do this?

I've added an example OmniGraffle shape below, showing some arbitrarily close control points and selection handles for the point of illustration. In my real example, the control points are completely covered.

Answer 1

The answer to your question is to Opt + Cmd + Click on the point you want to move. This will allow you to move the point without activating the selection handle.
