Use TAB key to parade through all possible controls located at the same cursor location.
For example, let’s say you axial sweep a shape along a path and later on you want to move the start point of the path, not the source.
When you place the cursor over the start location, with Show Controls ON, there are actually two different controls you can select at this location, the center control of the source shape and the start point of the path.
formZ will automatically choose the center of the source however if you hit the TAB key then the second control is selected, which is the start of the path.
