I know, but this is not very visual, I really like to have the different
region marked before I start any action. The multi-region looks very
much what I need, but the kill operation only works for one marked
region and append-next-kill does not work with this package (which is
very old, it is a miracle that it somehow still works, well it is Emacs
of course)

Ok thanks for pointint that out I will have  look and for sure use the
function you provided below
