This is awesome and really should be documented in the Help file. I’ve been missing functionality like this and wishing Obsidian had it. All along it did!
I don’t understand why this is part of workaround #3. It seems like it should be part of your last workaround (#4), right? Otherwise, I don’t understand what you’re saying here…there is no “selection” if you use Ctrl-C or Ctrl-X to copy or cut a paragraph that is not selected.
Anyways, so glad you posted this.
