The minor mode that resolved the issue at the top of this thread, for Steve?

This was a case where two of wanted a feature (that was present in emacs)
that we failed to find.

Thanks for the pointers to other sources.

Quite possibly.

The bottom line is that emacs has features that a large part of the user base
appears to be unaware of. I'm thinking it may be possible to generate some
form of documentation that might just put multiple pointers to a mode,
a variable
or some part of emacs that provides the feature that we only have an idea of
in our head. My term for this would would most likely be 'auto-reload' or some
such, i.e. when the file changes on disk, reload it.
For this instance the mapping is from 'reload' through to revert or

I was, you've pointed out 3 or 4 other places to look.
The main point is that your keywords and mine/Steves or any other uses keywords
are going to vary depending on background?

If thats believed to be the most appropriate place then fine.
I'd find it hard to see how you'll collect other peoples understanding of
the keywords. That's why I suggested a wiki approach or webpage.

I find the emacs info pages a pain to navigate compared to searchable,
indexable html pages derived from indexed xml. That's my bias I guess.

I was trying to be helpful Eli.
