Thanks Kay @KRMeadows ,
But ‘Exclude Non-Selectable’ does not have to be on. You can turn it on if you want to, it will just make sure, that you can’t snap to something that is set to not be selectable (the ‘arrowhead’ in the Outliner greyed out; like Background Images for instance often are set to, or if you have used a Bounding Box as visual aid, you might not want to accidentally select that, or snap to it).
So its actually the default settings you need to use 😉
