*which will then be used. (zzz :))
You can also check and see if it's nil and, if so, set it to
something else. This can be used to give it a default value,
one can have one for interactive use, and one for
non-interactive, or the same for both.
Here OTOH it's not an shame to one's family to do differently,
on the contrary that can make a lot of sense. E.g.,
interactively the default can be (point) if that feels
intuitive, while non-interactively that would be better set to
(point-min).
Again see this file and I'm happy to add more/better
examples ...
