The way I solve this problem is by calling `outline-back-to-heading'
(which, strangely, is not an interactive command).  After that, I have
access to all “speed keys”.  This works almost like a transient keymap.

Actually, I have a DWIM command that calls `outline-up-heading' if
already at a heading and `outline-back-to-heading' otherwise.  I'm not
sure whether such a command would be deemed generally useful or just a
bit too weird.
