* A macro would definitely do this--a "keyboard macro" solution is simple:
To create a keyboard macro do something like this:
Cx ( ....etc. Cx ) ; Mx name-last-keyboard-macro....etc.
To me, Cx (.....Cx )...--creating a "keyboard macro" seems to be the most
useful thing one can use Editor MACroS/Emacs for!
;-)
** The solution is simple because of the features of OrgMode--the function
of folding tree-nodes, makes it more simple than you might think:
*** Have the macro do something like this:
1. Fold everything up to just the major headings.
2. Go to just below "* A" and put a string like "jjj"--and/or Mx
set-mark--on its own line
3. Go down one row and do Ck.
4. MS< == EscapeShiftLessThanSign ---i.e. have macro repeatedly go to the
top.
5. Cy
6. Cs jjj
7. Repeat 3->7.
(Make 2 macros: The first does steps 1 and 2 and then does Cu 10000
macro-that-you-make-that-does-Ck-on-next-line-and-go-to-the-top ---i.e.
steps 3-6.
This way you have 1 macro call the other macro 10000 times or until you run
out of lines/major sections whichever happens first.)
You can make a macro that does the above--or just the second part and do:
Cu 10000 Mx blah-new-macro-that-reverses-the-section-headings
--then it would process a 10k major-headings-long-document or halt and "ring
the bell" when you run out of major headings to process--DownArrow will hit
the EndOfFile. Then you have a reusable macro that does what you want--with
all the subtrees/subsections just where they started--untouched.
I agree with Nicolas below, and his solution is generally what one might
seek; but, a "keyboard macro" here allows you to do what you described
without sorting or alphabetizing, etc.---the last major heading becomes the
first and the first major heading becomes the last, regardless of the
contents. Once keyboard macros are named and placed in .emacs, they are
reusable.
Good luck.
