(Not sure if bug-gnu-emacs is the right place to send things like this,
please let me know if there is a better list.)

I have been missing a article process mark toggle for a while and would
like to propose the below patch. If "+" is not an appropriate key to use
for this, I am happy to accept an alternative.

Hm.  A toggle command for the process mark?  I'm not quite sure I see
the utility, and it's unusual in a Gnus marking context -- none of the
other marking commands toggle (like setting the tick mark).

And the `+' key isn't very mnemonic for a command that toggles the `#'
mark.

i for one would use it.  in my case, it's very common that i've marked
an article by mistake (for instance when marking several for deletion).

i always forget it doesn't work, but my expectation is always that # on

Same here. My hands keep doing this, despite the fact that it never
works. Given that "add mark" on an already-marked article is a no-op, it
seems like it wouldn't hurt to have it toggle.

That'd be highly surprising if you say `C-u 10 #' and you have some
already-marked articles, etc.

Dired already works like this, and it is already highly surprising :)

i guess suprise is in the eye of the beholder :) i think that, in my
case, it'd do exactly what i expect (for the very little that's worth).

The downloadable mark is a toggle and because `@' is right next to `#'
(at least on the US keyboard), I frequently mistyped it and noticed that
the behavior is different.

Let me explain how I use the process mark and why a toggle is useful to
me. When processing a large number of messages, I sometimes mark a
region (or multiple regions) and then want to remove the process mark
from some messages in the region and add it to some other ones outside
the region. I can absolutely use `#' and `M-#`, but switching between
the two quickly when going through dozens of messages requires a fair
amount of dexterity. That's why I would rather mark the largest region
with the most messages and then pick out the ones to add/remove with a
single key that toggles the process mark.

I considered if this also makes sense for group and topic marking, but
it's an optimization for processing a large number of items, which is
why it is probably primarily useful in summary mode.

I saw the `+' glyph as a piece of a `#', which is why I suggested it.

It seems like many people would prefer to have the `#' command be a
toggle.  Perhaps we should just add a user option to have `#' toggle or
not?  (Defaulting to "not toggle" for backwards compatibility.)

Would it be too confusing to have it behave as a toggle with no prefix,
but "always mark multiple articles" when used with a numeric prefix?

To complicate things further, I think it would be worth making sure that
group marking in *Group* and article marking in *Summary* work the same.
This stuff is super prone to muscle memory, that consistency would be
nice.

2¢...

Some people in this thread said they wanted mass marking also to work as
a toggle.

Indeed.

Looks good.  Some small comments:

Perhaps this should be gnus-process-mark-toggle and also work in the
Group buffer?

We shouldn't check against t in either of these cases -- any non-nil
value is valid.

That makes sense and I can look at that. I have not dug into the
differences between group and topic mode, but I hope they are similar
enough.

See below. I tried to make sure that only `#' changes behavior and not
`M-#' (this is why there is a `no-toggle' variable for some of the
functions.) Have a look and let me know what you think.
