Theme: Pad, soldering point, via, plated-through hole

How do I delete an air wire (ratsnest)? I am working without schematic.
Double-click on the soldering pad that is to be disconnected from the signal. The dialog "Change Pads" appears. Here you delete the signal name in the "Signal" field:

1 (Image 1: The dialog: Change Pads)

If the dialog "Change package" appears instead, you have to switch off "
Select entire component".
