Hi mhtritter,
From the beta release note page [url]Scrivener 3.0 Beta - Release Candidate 10 (Download Links & Change List)]
“We have not yet updated the user manual, so the beta still contains the old 1.9.7 manual. We have however included an updated interactive tutorial for 3.0, which we recommend working through to familiarise yourself with the new features.” (bolding mine)
The status of the manual was already mentioned upthread, but I thought a cite would be appropriate. Your best bet on understanding intended functionality of the beta is to review the beta tutorial and release notes, and utilize the current Mac v3 manual, with the understanding that there will always be some Win vs. Mac differences.
As a data point for you, I also viewed this as a complaint.
Regards,
Jim
