Dear all,
I would like, by pressing the speed command N, to be brought to the next
NEXT headline. I can see that somehow the functions involved could
be org-match-sparse-tree and next-error, but I don't know how to code a
programmatic execution of the two (unfortunately I don't speak elisp very
well) into a function that can then be specified in
the org-speed-commands-user customization.

Is there anybody so kind to guide me to the (probably trivial) solution?

Thanks,

Giacomo
