As I type content under the current header, I often realize that I would like to rename the header --- give it a title more fitting to what I have written. One option is to get up to the header (outline-up-heading), delete the headline text and replace. For obvious reasons, it is often desirable not to leave where I am writing. I'd like to develop a function that will query for a new title in the mode line, and upon entering new title, the headline text is renamed. Is there such a function? If not, any helpful suggestions?
