If you link an object to the dummy, the dummy becomes its parent and the object is the dummy's child.
If you want to link an object to another one, select the object, then select 'select and link' (next to the redo button), press the 'h' key, select the object you want to link the other one to and press the 'link' button.
There are also other methods to link objects, but I'm not going to list all of them here.
The 'child' button is for selecting every child of a parent when the parent is selected.
