hyperlinks in PDF

[Alan Bowen]

Using the \setupinteraction and \useURL commands, I can  now generate 
active blue email links my PDFs—which is very cool. The downside is 
that my footnote numbers (both in the text and below) are now blue too.

I can go two ways with this. One way would be to set the footnote links 
to toggle between the footnote call in the text and the footnote 
itself. The other would be to prevent ConTeXt from treating the 
footnote numbers as links. I have no idea about how to do either and 
would be grateful for suggestions for either strategy, though my 
preference would be for the first (assuming that it is possible).

As it is now, clicking on the footnote call in the text changes the 
magnification so that the whole page fits on the screen, which is not 
all that desirable under the present circumstances.

since i'm in the middle of implementing some new nice interactive trickery 
i cannot upload a new version now, so you have to patch:

support)

[Alan Bowen]

Hans—

This is wonderful. I installed ConTeXt beta (to ensure support for  
multiple footnote types) and used the patch. Problem solved! The  
footnote numbers are showing/behaving properly. So we are now just  
about ready to go online.

Many thanks.

Alan

PS: What version number will ConTeXt have when there is no need for the  
patch? A.
