Hello Alan!

Yes, i know, it is because I am working with Word until now, but would like to change to ConTeXt.  If I set there a footnote, then there comes an pop-up window with the text. 

A Discussion would be very interesting. 

Thanks a lot. 

Ursula Hermann

It is an interesting comment going beyond the simple (yet important) question of accessibility: how in general should items such as footnotes be handled in alternative, non-printed formats, where the notion of a "page" becomes fuzzy?

With ConTeXt, it is easy to have such "footnotes" placed at the bottom of the formatted page, at the end of a section, chapter or book. It is also easy for them to have hyperlinks to jump to their location and then back to the reference text.

Tooltips and other widgets, as Hans says, depend on the display client and not on the document - there are many things that might work with one reader (i.e. Adobe) and not on others. Addressing the questions of accessibility, in particular for blind or otherwise vision-impaired readers, one can design an appropriate action or model for the document. Footnotes and endnotes are useful tools for a writer. Like indexes, bibliographic references, or floating figures or tables, these are concepts that might require some thought as to how they might be employed in an ebook or by an audio reader. This would make an interesting topic of discussion for our next ConTeXt users' meeting.

If your question is of interest to others as well, please add an entry to the Wiki!
