[Message part 1 (text/plain, inline)]

It would be valuable to mark the default entry when users scroll through the options
defined for `completing-read` whenever a DEF is supplied.

I'm not sure what you mean.

Is this about highlighting in `*Completions*' a
completion that's the DEF?

Is it about selecting (as the active region) the
DEF value when you insert it with `M-n'?

Something else?

And is the request to be able do whatever-it-is
_optionally_ or always?

Suppose one moves through the collection.  There is no way
that identifies the entry as being a designated DEF.

I think M-n ensured you are refering to DEF.

Optionally is ok, but do not know the technical details.  I do not think
doing it always would be a bad thing.

See below.

It would be valuable to mark the default entry when users scroll through the options defined for `completing-read` whenever a DEF is supplied.
I'm not sure what you mean.

Is this about highlighting in `*Completions*' a
completion that's the DEF?
Suppose one moves through the collection.  There is no way that identifies the entry as being a designated DEF.

By moving through the collection, what do you mean? Cycling among the matches to your input - e.g. empty input?

What do you mean by "moving" or "scrolling" through the "options" or the collection? Can you maybe give a recipe for doing that?

Is it about selecting (as the active region) the
DEF value when you insert it with `M-n'?
I think M-n ensured you are refering to DEF.

Of course. I was asking what you mean by "selecting" ("marking"). That particular guess was that you perhaps meant to have the DEF inserted by `M-n' be selected as the region. Sometimes "marking" in Emacs means selecting as the active region.

I guess now you're saying no, that's not it. So I still have the same question? What is this "marking" about?

Something else?

?

And is the request to be able do whatever-it-is
_optionally_ or always?
Optionally is ok, but do not know the technical details.  I do not think doing it always would be a bad thing.

Sorry, but I still don't know what this selecting or "marking" of a DEF entry is about. Maybe it's clear to others - hopefully it is.

This is for `M-n', I guess?

I'm not quite sure I see the use case here.  When do you want to have
the default value specially marked when going through `M-n'?

Again, what's the use case?  Why do you want the default to be singled
out in some way?

I'm curious too.  I don't say it couldn't be useful,
but I wonder what the aim is.

BTW, note that the default value (or even any of a
list of default values) provided need not be among
the candidates for completion, if completion is lax
(REQUIRE-MATCH = nil).  E.g.:

(completing-read "q: " '("a" "b" "c" "d")
                 nil nil nil nil "e")

It is a different thing than that.  I customarily using the `up' and `down' key
to move through the collection of entries.  Could there be some form of indicator
(e.g. highlight, underline, some other means) that will tell me that is was selected
as the default by the package designer?  Currently I see no distinction, with all 
entries in collection as just an entry like any other.

Wouldn't one normally associate a default with some sensible setting worth looking
into most times?  Perhaps this could be a user setting.

I see.  So the use case is to be able to check what
the default value is, so you can try to understand
why it's considered particularly useful.

For that, I'd think that `M-n' suffices, to see
what the default value is (the first default value,
if there are several).

Again, the default value need not even be one of
the choices (completion candidates), in the case of
lax completion (e.g. `C-x b').  I'd think that the
best way to find out what the default is would be
`M-n'.

(Just one opinion, and I may still be missing something.)

If not one of the choices, then there will be no indicator on any
entry in the collection.  

I think it usually takes some time to discover the `M-n' way.

It is just an observation.  Another way is to depend on the designer
describing typical use if attentive enough to include that information.

I think that the suggestion could make one's acquaintance with the package
speedier if there are suggestions on well designed settings.

I think the conclusion here is that there didn't seem to be a compelling
use case for this proposed functionality, so I'm closing this bug
report.
