Could someone please take a look at this?

Dear list members,
is there any way to get a cross reference to a column in a two

yes and no:
no : there is not something buil tin
yes: one can write some hack in a few lines
but instead of posting such a hack (which then will a live of its
own) i'll add a feature:
\pagereference[column:#1]
\doifelsereferencefound{column:#1}{\number\referencecolumnnumber}{}
in the next beta,

Thanks for implementing this, but I am afraid it does not work
properly, at least not if there are several targets following one
after another.
Consider this example:
\setupcolumns[
n=2,
]
\setuplinenumbering[
step=5,
method=page,
]
\def\Lab#1{%
\pagereference[#1]%
\pagereference[column:#1]%
\someline[#1]%
}
\def\Ref#1{
page \at[#1],
column
\doifelsereferencefound{column:#1}{\number\referencecolumnnumber}{},
line \inlinerange[#1].
}
\starttext
\startcolumns
\startlinenumbering
REFERENCES:\par
A: \Ref{A}\par
B: \Ref{B}\par
C: \Ref{C}\par
D: \Ref{D}\par
E: \Ref{E}\par
F: \Ref{F}\par
\input lorem
TARGETS:
\Lab{A} A,
\Lab{B} B,
\Lab{C} C.
\input lorem
TARGETS:
\Lab{D} D,
\Lab{E} E,
\Lab{F} F.
\input lorem
\stoplinenumbering
\stopcolumns
\stoptext
As you will see, targets A, B and C are all in the first column, and
targets D, E and F are all in the second column. But the references
read as follows:
A: page 1, column 1, line 29.
B: page 1, column 1, line 29.
C: page 1, column 2, line 29.
D: page 1, column 2, line 14.
E: page 1, column 3, line 14.
F: page 1, column 3, line 14.
Best regards,
Oliver
At least, I would need to get some value that tells me whether the
target is in the left or in the right column. How to achieve this?
This is the more simplified version of the my previous question
cited below.
Best regards,
Oliver.

Dear list members,
how can I create cross references to column numbers?
I have a two column layout with column numbers in the header
instead of page numbers (actually, these column numbers are
calculated from the page numbers). Now I want to create a cross
reference that returns the column number of the target. How can I
achieve this?
Of course, I can get the page number with \pagereference (for the
target) and \at (for the reference), but for calculating the
column number (according to what I did in the header), I would
also need to know whether the target is in the left or in the
right column, and I can't see how I can get this information.
For an example, see the question posted by me at stackexchange:
https://tex.stackexchange.com/questions/502944/context-cross-references-to-column-numbers
Besides, I am wondering, regarding the generally very regular and
consistent naming of commands in ConTeXt, why this is not so in
the case of references. For example, to refer to a page, I need
\pagereference (for the target) and \at (for the reference); to
refer to a line, I need \someline (for the target) and \inline
(for the reference), but only if I want it to automatically add
the word "line" or something else before the number, otherwise I
have to use \inlinerange. It took me some time to find that out.
Wouldn't it be easier to have just one command for the target and
another one for the reference, and everything else, as counters
and headers to be returned, text to be added etc. to be configured
by options?
Because all these \in \at \about ... give back different things (a
title, a number, a range, a ...) and packaging all that in one macro
doens't make it cleaner so soon users will then wrap complex calls in
a macro of their own (which then can clash with some existing name).
Also, the ref mechanism evolved over decades and we're not going to
drop compatibility.
