I think I have finally got this tracker/selection thing working. For example 3 stacking slabs and you want to extend the edge of one slab. I prefer to turn off the magnet and activate it with the spacebar.
Hover over the edge with the arrow pointer that you want to extend, the highlighted element appears in the tracker. Tab until you come to the element you wnat. Click the mouse and the tracker will tell you that you have selected the element. Click again with the mercedes and the pet palette appears. You can also do the same at a node.
