Re: Overalays and point-entered

[Nathaniel Flath]

Well, you'd want it to display when you moved to the buffer - If you are moving out of the overlay in question with C-x o it may not matter, but if you are moving into a window with a buffer that the point is in one of these overlays you'd want the action to trigger and display the error message.  The same applies to C-x b.  This was just the use case I had in mind - there are probably others.

Hmmm.... it doesn't seem clear to me why you'd want it for C-x o but not
for C-x b.  Aren't there other potential use-cases?
