I have the following question about references.
Using for example \at one can say somehting like "see on \at{page}[ref] for the figure..
But when the figure is one the same page it seems a bit superfluous to reference to it. In the same manner it is a bit of an overkill to put a hyperlink to the page where this link resides itself.
It is clear that ConTeXt knows if it is on the same page as is referenced, because then a link is coloured with contrastcolor instead of color.
Now the question: how easy/difficult is it to either suppress such an \at-reference or switch between chosen alternate texts for links on or off the same page as the referenced item?

Thanks Wolfgang for the code.
Just in case it is of use I concocted my variation on this theme. Now this simply replaces the \in, \at and \about macro's with one that does not show on the page where the link originates, but behaves as of old everywhere else. I introduced the unskip in order to remove the space that ruins the end of a line when there is nothing to display. For example from \in{see there}[ref]. <--this period would otherwise acquire a space before it.
\def\SamePageDo#1[#2]%
{\doifreferencefoundelse{#2}
{\ifnum\referencepagestate=1
\unskip%\unknown % reference is on the same page
\else
#1[#2]%
\fi}
{\unskip}} % reference not found
\let\oldin=\in
\let\oldat=\at
\let\oldabout=\about
\def\in{\SamePageDo\oldin}
\def\at{\SamePageDo\oldat}
\def\about{\SamePageDo\oldabout}

Instead of \unskip you should use \removeunwantedspaces which does a check before it calls \unskip.

Don’t redefine \in, at and \about because all three commands can also be used in math mode where they have a different meaning but with your redefinition they can’t be used anymore for math.

Hi,
I have small tabulations which contain references to footnotes in the
header line. - The footnotes are placed correctly, how ever if I
refer to the references I get in 2 out of the three cases ?? i.e.
ConTeXt does not know the reference. I am puzzled because it works
for the third reference... When extending the list of footnotes again
the referencing works only for the last reference.
Is there something changed in the approach in MKIV?
\starttext
\starttabulate[|l|c|r|r|r|]
\NC Issue \NC Time \NC Avg.\footnote[av]{Average log\low{10} values}
\NC s\footnote[stdv]{Standard deviation} \NC se\footnote[se]{Standard
error of the mean} \NC\NR
\NC A \EQ 1 \NC 3.85 \NC 1.06 \NC 0.31 \NC\NR
\stoptabulate
\starttabulate[|l|c|r|r|r|]
\NC Issue \NC Time \NC Avg.\note[av] \NC s\note[stdv] \NC se\note[se]
\NC\NR
\NC B \EQ 1 \NC 1.18 \NC 0.8 \NC 0.23 \NC\NR
\stoptabulate
Look at s\note[av]
\stoptext
I am using:
This is LuaTeX, Version beta-0.50.0-2009122422
ConTeXt ver: 2010.01.03 12:54 MKIV fmt: 2010.1.4 int: english/english
Kind regards
Willi

Hello,
I start with a small documentation bug:
in core-ref.tex there is a figure whose handle is [three calls]
which is later referenced by [fig:three calls]. This of course
means that the references remains unknown.
While this is (currently) a bug, it gives ground to an interesting
idea, connected to reference prefix: it should be possible to
allow different kind of stuff to have different automatic
prefixes, in such a way that [three calls] would be automatically
prefixed by fig: for a picture, tab: for a table and so on and so
forth (of course, customizable autoprefixes).
Of course, if such a feature is implemented (or even if it is not
implemented, actually) \definereferenceformat should include an
option to automatically add a particular prefix; so, if tab is
the prefix for tables, I could do the following:
=====================================================================
\setupfloat[table][interactionprefix=tab]
\placetable[here][handle]
{Caption}
\starttable
...
\stoptable
As seen in~\in Table[tab:handle], we have such and so.
\definereferenceformat[intable][text=Table,prefix=tab]
As seen in~\intable[handle], we have such and so.
=====================================================================
(hope this is clear).
While we're at it, I'd ask one more thing: how do I extract the
part/chapter/section/subsection/etc number of a reference?
