I'm using Windows 10 for an OS. For the instructions for full backup in the thread, I'm not familiar with enscript. As for right clicking, I've learned here that it only works for the lowest level (non-stacked) Notebooks, for a long time user its not exciting to have to right click on 76 Notebooks each time.
I long ago decided to live with selecting all and losing notebook context but at least be able save the notes. Had put in a feature request to have a one-action export that retained Notebook structure, but instead it now doesn't even allow a flat export. sigh. Thanks for your help.
