When multiple overlapping objects are accessible by clicking on a pixel on the screen, drag&drop operations may become harder to do: pcb-rnd will often "pick the wrong object" on click.

Cycledraw provides a way to get pcb-rnd to jump to selecting another object of the avaialble ones on the original site, while the user is still in drag mode. This obviously works only through the key binding, as selecting the menu would require the drag operation to finish first.
