Active point (red dot): The first point on which you click with the mouse becomes the "active point". This point is considered as reference point for functions such as "move", "copy", "rotate", etc.
Define the active point yourself: The active point can be redefined with Ctrl + inside the active element.
Active segment (white dotted line): The segment of an element that has been clicked on becomes the "active segment". The nearest point also becomes active.

The active point can be retained if the other elements are activated with Shift + + Lasso.
The active point can be transferred to another active element with ALT & L
