I'm aware of that.  I thought something Emacs tried to accomplish was
make analogous operations be performed by the same keystrokes.  Like, in
dired `^' takes me up "one hierarchy level" while in Gnus it also takes
me up "one hierarchy level", but those levels are completely different

This is why I thought that the expand/collapse functionality of
different modes might make sense to all use the same keystrokes.

Well, I'll be damned.  I didn't see it in C-h m.
