One question...

Theme: Track, conductor path

How can I delete all tracks on one strike?
This is very simple: If you are dissatisfied with the work of the Autorouter or with the tracks you have laid yourself, type [Ctrl] + [a] to mark everything. Now press [Del] to delete. TARGET first deletes only the tracks that the Autorouter has placed. Then type [Del] again and TARGET also deletes the tracks you had manually placed.. If you now type [Del] again, the parts will disappear.

So deleting by [Del] is multi-level: First, the "least valuable one" is deleted. But note: For example, if you have only selected parts and no tracks, the parts will be deleted already by the first clicking of [Del].
