When I originally proposed the outline cycling commands I
suggested C-TAB and S-TAB which I've been using for several
years.  C-TAB was rejected because it doesn't work in the
terminal.  I'm GUI only (macport) and haven't tried Emacs 28
yet, but if I find TAB conflicting with things, I hope it's
easy for me to change it to C-TAB and have it work anywhere
on the line.

I understand not wanting terminal to be a second-class
citizen (and that it has many users), but I wish its
limitations weren't so constraining on the GUI.
